FF 7 will not load in PS CS5

I just bought (finally!) FF7 and I get the error message:


<class XFW::ArgumentError> The handle 000000000013BDD0 is not a valid window handle.
It generates this as a bug report:

So I looked around to see if I could find the solution and this is what I tried:

1. Go to the Filter Forge folder in the Plugins folder of your PS CS5.
2. Find the Filter Forge.config file.
3. Open the file.
4. In the IndependentUI line, if the value is false, change it manually to true.
5. Save the changes in the file and try running the Filter Forge plugin again -- this might help.

I also uninstalled and reinstalled it

I am using it as a filter with Adobe PS CS5
It works as stand alone.

I have been using FF3 up till now.
Funny thing is, in December last year, I downloaded the trail version of FF7 and used it for a while. Then the error message showed up and I thought it was because the 30 days was up, but I guess not.

Please help.
