so i'm kind of in a bind right now.. i'm trying to audition for a band. they are sending me all the material in .gpx (guitar pro 6 files) and i can't open the files. i have guitar pro 5 and tuxguitar, but neither can open the new file type. i asked if they could just save they files as .gp5. they said no, they'd have to re-tab it in gp5. i don't know if that's true or not. so my question is, can anyone help me view these files? or convert them to .gp5 for me? i don't have the extra money to upgrade, plus i never use the program anyway. any help much appreciated!
