Ok fine.

Update your direct X

Make sure you're an admin

Compatibly mode doesnt matter at all.

Use partition magic and create yourself a windows Xp partition of about 5 GB and just put PSOBB on it. You can also run it via a virtual machine so you can run PSOBB via XP while still being under 7. This will work no matter what. However almost all of us are on windows 7 now and it works.

Also if you have more than 1 video card in your system you need to disable one of them PSOBB only works with 1 video card. That was stopping me for awhile.

Could possibly be the packer, check the pm I sent you to resolve that if it is the case.
