I can't open animate files!!!

Hi everyone, this is my problem.
I was working with Animate in Windows 7 without any problem, but over the weekend I had to reformat my PC and installed Windows XP, the problem is that I could not open the files because ANIMATE was asking me for extension files. SOLO or. DIGITAL and the files that I have are. TBUP

Does anyone know what might be happening?

P.S: sorry for my English.

Hi, Paul,
What’s your Animate file format ?
Did you save the entire project folder instead of just tbp files ?
Where did you get the tbup files ?
