Same for me, had CTDs continuously upon loading into any mission, sent a huge pile of crash reports, was already hyperventilating... - you can't do this to me during Tomcat Week!
Unchecking Enable LotAtc in Options' Special tab fixed it for me as well.
So I guess it only affects people having the LotAtc Server installed.
That shouldn't be many, but on the other hand a larger percentage of server hosts... - please fix this!
