Yeah, I forgotten to tell you that files are now stored in "C:\Users\User_Name\Documents\My TI Files" instead of "C:\Program Files\TiLP\My TI Files".
Please note this beta does not localize the folder name yet (eg "My TI Files").
There is a small incompatibility between TiLP and Vista about disk management. If needed, you can download a (unofficial) release of tilp which works under Vista.
