Sorry John, I thought it would be helpful for you as long as the cause of CTD is not clear BUT it definitely has to do with FSUIPC 7 . See the answer of ASOBO. Sorry - I#m not a programmer, - I see only that my main programmes, maps etc. is not working anymore . I'm a registered user of FSUIPC, means - I pay for the product. That may not be a "fault" of anyone but there is something wrong since last asobo update.
Answer from Asobo/MS Helpdesk:Hi Hsauer,Thanks for contacting Microsoft Flight Simulator Support today. There is indeed a known issue with FSUIPC7 since the last update that is causing crashes. The root cause is being researched.Kind regards,Microsoft Flight Simulator Support Team
