I downloaded the MR3 release and was even able to build is successfully on my machine. But I was unable to execute it. After building, on running runPhoneME.bat I get the message saying "sublime.dll" is not found..
I then put sublime.dll in the system32 folder(just try) and on running runPhoneME.bat again, it says:
[CRIT] [core ] Illegal argument to KVM: internal
