Hi guys, Recently I bought the PMDG 777 and unfortunately my FSX is getting fatal errors at unpredictable moments during (and sometimes after) flights. I have read a lot about fatal errors and the UIautomationcore.dll is not the problem causing it. It happens during panel state changes in the NGX and currently when setting up the fmc of the 777 too. The crash report stated the problems in a ''language'' I could not understand ..... Hope somebody can help me out! ***DO NOT PAY ATTENTION TO MY PC USERNAME,.. ITS A JOKE BY MY BEST FRIEND, STILL HAVE TO CHANGE IT BACK...*** (sorry...) A printscreen of the event can be found in the attachment. I was not able to upload the report .wer file, dont know why. Thanks in advance David, Amsterdam
