I have the same issue since yesterday on the MFC0029 leg from AK75 to PASH. Some seconds after take off CigarBox freezes completely and must be killed by the task manager.
I filed a Charter Flight from AK75 to PASH with the same result.
I started the leg before at PAOT which was no problem a few days ago (with the BID of MFC29) and Cigarbox crashed again.
I think it must be a server problem rather than an individual issue.
I actually ran MFC 29 twice
