So after a long time I have installed UP3-RC4 ( finally weaning myself from Mod Activator).
Only enabled UP3 and Haken ; didn't install ANY mods.
For a couple of days no problem. QMB , FMB ok - checking out the list of aircraft and maps from UP3-RC4 and HSFX5.01 to compare. Flew for hours , about 10 missions in QMB and designed and flew about 8 missions in FMB.
In FMB I tried to make a mission for He 219 Uhu and forgot to make the mission with another AC then change to He 219 in the Aircraft Type menu - got the old FMB freeze that used to occur to some AC mods ( I didn't expect it - thought it might have been corrected for the big install). Open Task Manager , close UP , restart UP , rebuild mission , fly no problem.
Next time I try QMB I get the message in the Subject Header " Mission Failed : Null" (note this occurs AFTER the mission loads past "90% Loading Humans".
I tried all the maps in the QMB and altered all the aircraft one at a time to aircraft that I had already been flying in this install to eliminate them (maps , planes) from the equation. No joy.
Now I cannot fly in QMB at all.
FMB seems to be fine.
Any ideas from anyone?
