by random, i get this error saying "MapFile1: Access is Denied." i know this is caused by atitool, but does anyone know anyway of avoiding this? or stopping this?
Try uninstalling and reinstalling it if you can. Certain tools and applications can be removed and reinstalled. That's my best guess for now. I can look more into it if you need.
Was this error recent? Perhaps, a system restore might do the trick.
