Have you asked for assistance on the main vBulletin.com forums? There are forum areas where members and staff will be more than willing to help with the errors encountered, but you must be willing to share the errors and await reply.

It sounds like you may have tried installing this and perhaps configured it wrong during initial installation which can cause errors, there could also be issues with your hosting... or rather.. not issues but perquisites not met such as a specific PHP or MySQL version, there is a lot here we don't know - including all the errors and why you became so frustrated. Many factors, but one that I do like to see which is you liking something that you purchased (Xenforo) so I hope you didn't run into any issues installing it and things went smoother.

Consider using your vBulletin license for something else! You may find it useful for another type of site, I see your username which is interesting to say the least, perhaps a forum of another subject? So think outside the box and don't let your money go to waste, also were you aware you can install vBulletin 4 under that same vB5 license? You can so also consider that as you shouldn't have as many issues installing it, if all requirements are met beforehand.

All-in-all, again, just glad you have something usable!
