I was on the Live game today in Nordrilund, and my computer screen turned to a patch of glitchy colors and distorted images. The computer completely froze, and I had to restart in order to load Wizard again. This happened several times throughout the day, and the first occurcence was a single instance about a week ago. Does anyone know if this is Wizard messing up, or is it the hard drive?
It might just be Wizard that's gotten corrupted. You can try uninstalling and then re-installing Wizard101 (you won't lose any of your gear or characters, though it might take a bit for the game to download all of the textures and data for them again) to solve the problem.
