I just bought this game today and got home to install it, hoping to be able to play it. But while installing the game, at 51%, an error box popped up saying:
"The installer was unable to read the file "Repack-MPQ\fileset.enUS#Campaigns#Liberty.SC2Campaign#enU S.SC2Assets\Assets\Textures\cinematic_bettermarine .ogv". This error may be caused by problems with the media or drive at E:\--for example, a scratched or dirty CD-ROM/DVD-ROM, hard drive corruption, or a networking problem while downloading the installer. (The error code was 5.) If this problem persists, please contact Blizzard Technical Support. (ReadJob::Execute)"
At the bottom of the installer says "Cleaning up..."
I can see that the statement above says it could be a scratched or dirty CD, but come on, I just bought the game today.
Here is a picture:
