Hello.
Had this issue too. Yesterday all was fine. Today max start to crash on startup when loading corona.dlr. When uninstall corona - all fine, when install A6 - all fine, when install 1.0 or 1.00.01 - it crashes. Reinstall 3dsmax, install 1.0 - it crashes.
I solved a problem only by deleting folder: C:\Users\****\AppData\Local\Autodesk\3dsMax\2014 - 64bit
After that it start working. It happened only on 1 of 3 my pc, others works fine.
