Trouble while re-installing!

Hi!

At the company I am currently working, I've gotten the job to install Xara Webstyle 4 on some recently bought computers, (running XP). And we are having some great problems right now, moving the projects from the old computers to the new ones.

In the new computers I am able to browse through the projects, but I am not able to edit anything. And it is important for us to have these projects, and to be able to edit them and save them, in the future.

Is there anyone else who has got this problem?
Or any clue on how to solve my problem?

Cheers,
Artheus
