Need help with Sandboxie

I can't find an old version that works without buying a license and can't crack newer versions, I keeps telling me it is an incorrect serial...

Can someone upload something working here or give me a link to a tutorial or something

I would try that site (haven't tried it, I offer no guarantee there, and I didn't know you _had_ to buy latest version of sandboxie):

You have to insert a serial if you want to create more than one sandbox, what is exactly what we need to run rappelz multiple times, isn't it?

No, you run one sandboxed and one non sandboxed.

Have I really just been that stupid?
Can't believe it...
