ah yes.. the same reason I reverted back to 32bit Ubuntu. It was that silly little flash program. I also had an issue with my student version of Matlab so I too gave up and went to 32bit.
There was a way to run it using a plugin wrapper. I never did get that to work though. Maybe you will have better luck. Have you tried it?
