My window is locked up because I am getting this error and thus cannot scroll down for the rest:

EQ2MAP_Updater.exe
EQ2MAP_Updater.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
If you were in the middle of something, the information you were working on might be lost.

What do I do to make it start working again?
