Huhh Guys, thanks a lot, you saved my night. With your suggestions for the question No.1 i'm happy, absolutelly happy. Because have NT at work. Seems i have to stay up early in the morning to check this. And if it runs, i can do the CD-burning at work. If not then i save the needed NT files from my machine at work and try if i can do it with the NTFS-driver which mi-scha suggested. If this works, you don't know how much time and work you saved for me. It's more then 300 hours of modelling which is at the moment useless. Again, thanks a lot and please cross your fingers. SHARKEY
