Interesting. And it only ever fully crashes leaving this information in the Windows Event Viewer? Usually if it's a normal crash you will get a call stack with lines of code and line numbers.

The only XML stuff going on in MultiMiner is the configuration related bits. So as a test you could go into %appdata%\MultiMiner (put that into the address bar in Windows Explorer) and move / delete your XML configuration files.
