Texpand2 & Windows 7

Hi there, I normally use texpand2 to reset default textures in FS9.I have recently got a new computer now running Windows 7 64-Bit, installed texpand2 fine, but when I run the programme to copy the files from the original FS9 disc's, it creates the three folders but doesn't copy any of the files from the discs to the folder it creates, therefore I cannot use texpand2 to reinstall the original textures.I have tried running as normal and also by right clicking and run as administrator????Look forward to any replies and help.Kind RegardsGavin Moss
