After troubleshooting for the past 4 days about error 132 - I've reinstalled wow and have applied patch 4.0 successfully. Having been able to play yesterday, I'm not at the stage where the launcher is telling me there is 7.4gb of data requiring download before I play. I made sure I took all necessary files associated with 4.0 patch out into a folder on my desktop before wiping wow from my system. I've put all the files back into my wow folder where they were originally. Am I downloading unnecessarily? If so what are some suggestions to be able to play again? I don't think I need to download these files again but I'm not sure how I can get the game to recognise the files are already on my computer.
