FFR revolution just dont run to me

[Fidazul]

Hi.

Well, I´m in this forums since a week, but I play SM for long time ago. Now i´m playing FFR in the computer´s college in my free times. The thing is, when i´m in mi home, FFR (first version), R2, and Resonanse runs without any problem, but when i´m in the computer´s college FFR (first version) just dont run, and get stuck when the song are going to begin.
I dont have any problem with FFR R2 and FFR resonanse, but with the first version i just can´t play.

Why this happen??, need i to install something??.

thanks

P.S: sorry about my english, but i speak spanish (im from chile).
