answer:I really don’t think you want M3PLUGIN.DLL, so you may want to run ccleaner on your system and see if that takes care of the problem. From what I can see, you’ve got something that borders on being a virus (if it isn’t actually a virus). If you have an anti-virus program it probably deleted the .DLL but left the rest of the program there. So, when the program runs it can’t find the .DLL and pops up the message.
