@Woshilvba: Can you upload an screenshot with the exact error so Keymaster can take a look? usually that helps a lot because maybe the problem is somewhere else, think that max 2011 is a very old version of max (but if corona supports it it should be working nevertheless).
Also do you have the possibility to install 2012/13 or 14 and check if it works there (at least 14 in trial mode) to discard an specific 2011 problem.
I have to say that I don't work with keymaster, I say that because i'm asking for a screenshot so keymaster can watch it and maybe he don't need it, it's just that I think this can help Keymaster to understand what is happening and it can help us to help you to solve the problem (after many years of alpha/beta testing other packages )
Also another thing that can help is a video instead of a picture, and also another thing that can help to discard other problems is to make a clean install of max.
BTW when you start max, the crash is just for corona but you can work with max, or does it crashes max completely? If it's the latter, does it brings you a CER windows? (I think you can see the CER details, but I'm not sure about that, i don't remember exactly)
Other possibility is some kind of incompatibility with another plugin (but that's weird because many more people could be having the same problem)
I hope this can bring some light into the table, these kind of errors are a pain in the ass and usually are silly things like a missplaced file or similar :P
Cheers.
