Can you tell me when it is crashing? Are you able to launch the application?
A crash report feature has been added in uTool, it is preparing an email with the report file attached during a launch following a crash. Then you just have to send it to give us useful information to fix the problem.
If uTool is crashing when you launch it, please delete the file “uTool2CrashReport.txt” that should be located in Documents and SettingsusernameApplication DataCymatic Audio uTool2CrashLog (on Windows) or ~/Library/Cymatic Audio uTool2/CrashLog (on Mac). Then check your email setting, the crash could be caused when uTool is trying to setup the email.
