This isn't as slimy as it sounds - but is there any way to reuse a Parallels trial? I'm not trying to avoid buying it, it's just that due to life getting in the way, I never actually got to use my trial, and I would still really like to try it before I buy it to make sure it does what I need. I've tried registering with other emails and so on, but every time I install the program, it seems to know that I have had it installed on my system at some point. Is there a file hiding around somewhere that I need to get rid of first? I have uninstalled it as thoroughly as I know how before attempting to reinstall, and I've tried using another user account.
