If you have troubles with UDOBot crashing then do the following:
"Right Click UDOBot.exe->Properties"
In the Properties, select the "Compatibility" Tab.
Now you have to test around, try all various Compatibilities, it has helped many to resolve the crash Bug.
E.G: Try Windows XP SP2 (some say it has resolved it for them).
I myself use Compatibility mode for Windows 2000, hasn't crashed since.
