I read somewhere that if you go into AE 6.5 and look under help > Text Preset Gallery that you can use and modify all those cool text animations. Whenever I try to do this, however, it gives my a dialog box that says something along the lines of the file not being found. I also looked into the presets folder for the file, but it said it wasn't an acceptable file type. Any help to help me solve my problem is greatly appreciated.

Is it pirated or the demo version? If it's the real thing, is it possible that you only installed the compact version and not the typical one?

Well I have all the files (.ffx). But AE won't let me open them, and it's the real thing.

A quick call to adobe should resolve this.
