I've read many threads, but none seems to solve my issue.
My KSP keeps crashing on startup only when MechJeb is one of the mods (or even the only mod)
I'm running Windows 10 x64 with GTX 970M and 16GB RAM, so hardware is not the issue (I hope)

output_log.txt

There are the error)log and output_log.
Please help

There is no MJ version compatible with 1.2.9

When will MJ be compatible with 1.2.9 ?

Days/weeks after the 1.3 release. KSP 1.2.9 are just re-releases for 1.3
