OnCourse Software

Yesterday, I tried a flight from Rotterdam EHRD to Hannover EDDV with the Digital Aviation Cheyenne IIXL, flight level 200. About 70 miles from destination I got the instruction to descend and maintain flight level 140. This was the last instruction, no speed restrictions, no further approach details. Here is what I found in the debug_monitor.log:

09.05.2010 18:09:55: 080 - PFE Version: 2.14.0
09.05.2010 18:09:55: 080 - APLC Version: 1.0.1
09.05.2010 18:09:55: 080 - FS Version: FSX
09.05.2010 18:09:55: 080 - FSUIPC Version: 4.570

09.05.2010 21:22:32: 580 - Transcript: 'Lufthansa Delta India Oscar Sierra Yankee Descend and maintain Flight Level 140'

09.05.2010 21:25:27: 720 - Checking speed reductions at RA 14016 and AppSpd at 140
09.05.2010 21:25:27: 770 - iClimb=0
09.05.2010 21:25:27: 780 - Checking track to last hdg change - Hdg: 75 Trg: 335
09.05.2010 21:25:29: 800 - Dist to Dest: 35.31529

and later:

09.05.2010 21:31:51: 090 - Checking speed reductions at RA 13805 and AppSpd at 140
09.05.2010 21:31:51: 130 - iClimb=0
09.05.2010 21:31:51: 160 - Checking track to last hdg change - Hdg: 73 Trg: 335
09.05.2010 21:31:53: 190 - Dist to Dest: 1.25184

BTW, what is this (I did no re-install of PFE or FSX; PFE-database is new as per instructions; FSX-ATC inactive):

09.05.2010 21:24:52: 830 - Error: 52 - Bad file name or number at 528 in AI_Interaction

What happened, why did I loose ATC contact?
Kind regards,
Michael
