So, after I spent a while in chat with a few people who had the issue, it happened to me as well. It seems to be related to your HB crashing and corrupting or something. The best way I found to fix it, including for myself, was to follow these steps IN ORDER. 1. Restart Computer 2. Delete HB folder 3. Re-extract HB to a new folder 4. Delete all CCs 5. Extract the cc you are using 6. Extract your profile 7. Delete C:\Program Files\World of Warcraft\Cache\ 8. Load WoW all the way into your character 9. Launch HB This worked for me. Make sure you restart your computer before you do anything else. If it doesn't work try it a few times, usually it works the first time, but a few have had to repeat it to make it work.
What is the reason for this? My wow crashes everytime I log into wow. Worked fine earlier today, but when I logged in the first time this evening there was a new patch (3.3.3a) wich was required, is that patch the reason?
i think the time taken to delete and reinstall is enough time for it to reset itself, from what i saw yesterday it happened to me when my WoW crashed and HB got a error.. basically i waited 5 - 10min and it reset itself and worked fine, no deleteing the folder, no resetting my comp, no deleting cache files or anything... i left it off for like a bit over 5min and it worked again
