Recently I bgan experiencing disconnect issues between FSX And MYAASv2 (most recent version). My flights would freeze up (FSX not respondng message) and my first suspicion was memory issues (occurs while flying PMDG A/C, with numerous other 3rd part addons running). FSX locks up (not responding) and results in having to exit FSX and trying to refly the route from the last saved point. Then after several of these incidents I finally looked down in the MYAASv2 box and saw it suggested checking for the most recent version of FSUIPC. So...I upgraded FSUIPC from v4.0 to v4.9 (released 2/10/15). Back into my flight route now. Fingers crossed this fixes the connect issue between FSX and MYAAS. Just posted this issue in the event anyone else has been experiencing the same.
Continuing my flight route, experienced another FSX lockup and MYAASv2 message cannot connect with FSX. So...the search continues for a solution.
