Hi Kumasasa,
The problem with crashing it is that the game never starts.
The problem may be related to permissions, particularly on Windows 8.
It is now fixed. A third JRE installation followed by running the MCL as an Administrator seems to have been the magic formula.
I recommend that anyone having this issue while using a non-Administrator account run the MCL the first time as an Administrator.
Thank you for your time,
Robert~
Key word here is "should". It does NOT. We, in fact, had installed the latest version prior to running the MCL, and again installed it via the link that was opened.
Therefore, this bug report needs to be reopened.
P.S. It may, or may not, make a difference that I had installed MCL 1.0.6 after I installed the JRE for the third time.
