'Windows - No Disk' Bug?

Hi, I didn't want to post this in the bug section in case it wasn't a bug. But I have ran my program fine on my computer Windows XP Pro SP2, and on my laptop Windows XP Media.

But I have also run it on two other machines, a Vista Home Premium and another Windows XP Media, and I get this error message. Just wondering if its me or blitz, and if anyone else have had this problem?

Oh, and if I click 'try again' or 'continue' it still loads up my program normally.

Are you using absolute paths somewhere? Maybe using an incorrect drive letter?

theres a couple of reasons for the message a quick google will help troubleshoot, i would say i dont think this is a blitz related problem.
