IS to 160 Post....still not fitting?

Hi all.
I've put hydraulic disc brakes (shimano deore) on my mtb.
The fork fitting is an IS mount. The brake caliper fitting is a post. The rotor is an avid 160mm.
For the forks I've bought a shimano 160 post to IS adaptor and tried to fit it. However, it doesn't fit.
It's almost like the rotor is too big or that the bottom of the mount doesn't come out enough (i've measured and remeasured the rotor and it's 160). I can get the top bolt in but the bottom (fork to adaptor) is miles away.
On the rear I've got it all sweet, but the front just won't go....
Is there a 3rd type of mount?....really confused as I've never encountered this before!

Pics?

I'll get some pics when at home later.
Adaptor is on the right way. Arrow pointing up as per instructions.....
I've not installed any spacers. I think they're flat mounted to the post mount. The back works perfectly like this. A stock photo shows the same set up I have:
It's such a simple thing and I have no idea what is wrong!
post up a picture.

point taken!!
I know it's not my bike, but work is slow today and I'm lacking motiviation. The pic below is the adaptor I've bought.
I have the arrow pointing up towards the bars. I've got it on so that the flat edge is against the forks, and the "cut out" piece (the side visible in this picture) is next to the rotor so that the flat surface meet with the brake mount.
It's a 160 rotor, 160 IS to post mount.....what could I possibly do wrong (apart from mount it upside down which I'm sure I haven't)?
Yes agreed. That will teach me not to skim read issues in future.
I saw the mention of avid disc, and assumed calipers also
without seeing what YOU have and what YOU have done we can not offer YOU any help with YOUR problem.
but we can say that yes that is the correct adaptor.
also knowing what make model and year of fork would be good.

I remember someone having adapter problems once, they said they put the adapter on the right way with the arrow pointing up, nobody could work it out what the problem was so I asked for them to post a photo, they did and the photo immediately showed that the adapter was on the wrong way around.
When the adapter was fitted to the fork the arrow was pointing up but the bike was upside down.
This view shows the distance the bolt is out from the hole:

No idea why the images aren't working - I've clicked the image button and pasted in the URL....

right in this case i would mount the adaptor and then get some washers and longer bolts and space the caliper out.

No idea why the adapter doesn't work but I agree with packing the caliper out to make it fit.
When fitting attach the adapter to the fork first and then attach the caliper to the adapter.
Er fail.

No fail if you can see the photos, that method worked for me.
Methods on how to do it can vary depending on your browser and if you have certain add ons.
Firefox with and the No Script add on it worked for me if No Script is active with Dropbox or you 'Temporarily allow dropbox.com', it won't work if you 'Allow dropbox.com', 'Temporarily allow all of this page' or 'Allow all of this page'.
On Firefox without the No Script add on.

Still confused why it's needed as everything is correct.....
And thanks for the tip on dropbox.....

Although I can still see 2 images that I posted I will agree that dropbox is a big fail for image hosting.
After a bit of reading it looks like you can get away with posting photos for a while but if too many people look at the image you'll run into problems.
Conclusion.
If you want to post photos do them through a website that actually lets you host images and don't use dropbox.
