Hi guys, i bought guitar pro 5 a couple months ago, and it seemed to work perfectly until yesterday. What it started doing is: each time i press the play button, to start the song, i see the RSE stuff load but it doesnt play, i just get that screen:

in case your wondering, the 3 buttons at the bottom are:

1. Contact tech support
2. Close guitar pro
3. Continue using guitar pro

so please if any of you know how to fix this please tell me.
If you really bought it why didn't you contact them? No wait, you didn't buy it didn't you?
i reinstalled and it works now, thanks guys

yes i really bought it and yes i realize i was stupid not thinking about reinstalling
