Problems with Microstudio 2.013 (Demo)

[Annie]

I installed the demo version and it worked fine until I turned off my machine. The next time I tried to run it - no go. I reinstalled, and it worked again, however this time, my machine rebooted as soon as the song stopped playing i.e. I got to see the message about the demo version only playing for 75 seconds, then the reboot.

I've seen that others have had the problem of not being able to run Microstudio, but has anyone experienced this rebooting problem?

Please can anyone help, as I would like to buy it to play my songs all the way through before burning (but not if this problem continues).

Thanks, Anne
