FF does not apper in Photoshop filter list PS 5.1 (CS 5.5)

Hello Community!

I recently upgraded my CS 5 to CS 5.5. Now I'm using Photoshop 5.1 64Bit on a Windows 7 system.
Since that change FF3 (3.007) unfortunately does not show up in Photoshop's filter menu any more.
I was searching the internet and in this forum for solutions. But all attempts too solve this problem by myself failed.

- I have already deinstalled FF3 and installed it again. => no result
- I copied the whole Filter Forge programm folder to ADOBE/PLUGINS/FILTERS = > no result
- I reseted the Photoshop configuration by pressing SHIFT+ALT+STRG while opening PS => no result
- Finally I contacted the Filter Form Team via the contact form on this site => I did not get any reply at all

I'm not satisfied with the support from FilterForge. I bought!!! FilterForge to use it with and especially out of Photoshop.

But FilterForge is a good software and I would like to use it further on. Therefore I would be very glad about any help to solve the

problem.
