read the instructions how to install them

Appreciated mate , was just about to reinstall and saw your post.Anyway I managed to watch some replays and learn cool tactics , tho some replays say replay Desynch ( human vs human ) . Thanks again.

Yeah , I deleted it and didnt want to re-dl , but seems I'll have to do it and upload the file for someone in the same boat as me.

Hey , as others suggested try to dust off your card. Also for monitoring gpu tempretures id suggest MSI Afterburner( http://event.msi.com/vga/afterburner/download.htm ) . You can control fan settings + monitor tempreture + over/downclock + modify your card voltage all in 1 tool ( it co-devolped with riva tuner ).
ps if you overclocked your voltage , be sure to bring it down as it gives more power to the card thus more heat generated.

Hey everyone , I'm new here. This site has been very helpful with the info about how to play sc2 without beta access.I wanted to ask if someone would be nice enough to upload his original Base.SC2DATA ( \StarCraft II Beta\Mods\Liberty.SC2Mod).Mine got replaced by starcrack and I didn't know that I would need it later on for watching human vs human replays.
Thanks in Advance
