After trying various edits per your reply, nothing changed, always crashed on startup.  So i did a completely fresh install of XP10.25 everything completely standard, no custom scenery, no plug-ins, no pay ware aircraft have yet been added to this fresh install.  Opened fine first time.  Then I installed SMP 1.1.  Crashed on startup.  Log.txt is attached.  Shows same error message that it did before. Log.txt
