Error: Can’t find Language DLL msain.dll
If you get this error after running a Windows update, give this a try:
If the Microsoft Access program is installed (rather than the runtime), locate Microsoft access from the start menu, programs. Open Microsoft access and let it initiate or configure itself. Close, then try running ProTracker again.
Or, go to the programs and features in the control panel. Locate the Microsoft office, right-click change or repair. If using the runtime, locate the runtime in the program list and run a repair.
If neither of the above options resolve the issue, try replacing the runtime file or switching to a different runtime version:http://help.protracker.com/entries/42409306
