Planetdance has nothing that's exceptional, it should just run fine on 99% of all pc's. If it doesn't however, the cause is hard to detect, there are just pc's that 'act funny', just some weird combination of things that make a pc unstable for planetdance, like in your case. I don't think you're gonna find a solution.
You could try and install windows on that pc, it's made for windows so it will work there.
