The search function has been down for a couple of days now, so you won't get any help there.
This has been a problem faced by many. First of all you need the "INDE Emulator" (I think) so you can enter your virtual cash in order to play. It may also be that its not compatible with Windows 7, so you could try running it in a compatibility mode.
Most of the issues and cures were discussed about a year and a half ago, like modifying the files so you don't need sonar, but with the search not working you could troll through the FORUM posts around that time for your answers. It's become somewhat of a tired subject now, so help may not come banging at you door.
One thing I will say...Skill Bingo very quickly becomes boring, and I believe most of the Paragon games never worked.
LOL Its not so boring when your throwing pound coins into it tho, supprisingly addictive
