Maybe the names of the directories are incompatible...
Like "mes documents" instead of "my documents" for the english version.
If this is the case, you could try to create a directory called "my documents" and put your stuff in there.
If this doesn't work, I suggest you give us a detailed listing of your directories...
And what is the error message? Maybe the gx.dll isn't installed right?
