Hi,I'm new to this forum and apologize if my problem have been reported before. I searched and couldn't find anything. I'm no english native, so errors in the writing may occur.My PC flight system is built up with Win XP Prof. SP3, FSX SP2 and ASE Build 647 (SP3).Yesterday I was flying the LDS767 from Toronto to Munich when, at about two hours after start, ASE ceased operation and wanted to report the issue to Microsoft, to which I agreed. Several tries of restarting ASE failed and so I continued my flight with a steady (but too weak) tailwind over the atlantic. On descent towards Munich Airport I tried again to start ASE and had luck: no error!After closing down everything at the gate, I had a look inside 'ASE_SimConnectionLog.txt' and found several lines with 'SIMCONNECT_EXCEPTION_DATA_ERROR'.Any help appreciated.Hans
