ACTIVE FSX SE Ceases Stating Unknown Windows Error At Exactly 1 hour 11 minutes

[Mojavi]

Flying the ERJ 135/145 Feelthere payware, FSX SE stops functioning at exactly 1 hour and 11 minutes no matter where I fly. This isn't a crash.  No explanation is provided.  A message window states an windows error has occurred and windows will attempt to provide a solution.  Doesn't provide anything except heartburn.  

 

I run an Intel Core i7-4790 4GHZ, 16GB 2600mhz ram, Windows 8.1 64 bit, and an EGVA Overclocked NVIDIA GeForce GTX 980 4GB. I run, FSX SE,  REX 4 Essentials Extreme HD,  and ORBX Global all at maxed out settings, sans DX10 (I can't resolve the black boxes festooned throughout the landscape yet, ergo one problem at a time).  I have zero stutters or latency or any indication of struggle from my machine.  At 1 hour and 11 minutes, a windows error message pops up, stating there was an unexpected error.  No specific reason is provided.  I installed the ORBX DLL update files - issue persists.  If anyone has any suggestions, I would really love to here them.  Thanks in advance for all the help!

I heard they were upgrading to an offline mode. That might solve it once they do. If not I would fill out a support ticket through their website.
