The game loads my charater, then screen goes blank. I may need to re-install the game and I worried about losing my charaters. So, how do I save my charaters and re-install? I will clean my computer, incase my video card is over heating. It may also be the window switching ability on my O.S.
Your Wizard is safely stored at Ravenwood School of Magical Arts. Even if you uninstall Wizard101 from your computer, your Wizard, all the belongings and experience earned is still safe.
When you reinstall, it may look like your Wizard is still wearing his/her starter outfit, but they're not, it just takes a little time for your computer to download all images of the clothing and items that you're wearing, so don't panic! You can verify that your Wizard is still wearing their higher level clothing by looking at it in your backpack.
