Ps2 Games Not Downloading

Hey, sorry for any inconvenience, but for some reason after I downloaded 1 ps2 game, the others will not download. I cant download the ps2 emulator either anymore. I can download other console's games tho. I have tried everything from restarting my computer, deleting my history and downloads cache, to trying different browsers. The only other thing I could think to do is delete the one game I have (yu-gi-oh rose duelist) but im worried it wont let me download it after I delete it.
