Error when opening COMSOL
 

Hello, I recently encountered a problem while opening COMSOL multiphysics which gave me and error, stating that an unexpected error has occured and that I should look to the end of the log file.

Here's the log file generated by COMSOL:

'.', hexadecimal value 0x00, is an invalid character.
at System.Xml.XmlEncodedRawTextWriter.InvalidXmlChar( Int32 ch, Char* pDst, Boolean entitize)

at System.Windows.Threading.ExceptionWrapper.Internal RealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatch When(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

So if anyone has an idea as to where this might be stemming from, any help would be appreciated. thanks in advance.

It seems to be a character that it doesn't understand. Maybe a system path is wrong?
