Cannot load most versions

downgrading is not supported
don't mark future version as effected you don't have access to them yet

I cannot do minecraft 1.8.8 either

Please attach the crash report

the crash report had to be created manually because minecraft does not count it as a crash.

would you like a snapshot of the problem?
