I recently installed a game called Warcraft III: The Frozen Throne so that I could play DotA Allstars. I played Warcraft then downloaded DotA from dotaportal. I discovered that the version of my Warcraft was not compatible with DotA so I tried patching it to version 1.11. When I tried to play the game, my computer issued me an error message that ruined my life: Please make sure that your Frozen Throne disc is in your CD-ROM, then click on 'Retry'. I tried in vain to solve my problem even patching it to 1.17 and 1.21 and asking help from a Blizzard Technical Support personnel but it still didn't work. Please help me: I don't know what's causing that cursed error message.
