Maybe once out of every 3 or 4 times I click drive to go on track, I get a CTD, Problem Event Name: APPCRASH, Fault Module Name: AMS.exe, etc. etc. I've probably had more than 10, maybe 15 (not exaggerating) crash-to-desktops just today alone playing AMS. I didn't seem to have the issue when I removed the motec plugin. Also, when I drive, I don't hear it say "motec activated" or whatever when I go out unless I'm in a test session (1 car). When I go out for practice session in a 22 car session, I don't hear the message. I read in a racedepartment thread that AMS will display a warning on screen if running low on memory but I've never seen this message, ever. I tried the patched DataAcquisitionPlugin for Motec v1.0.3 Motec and the original plugin for up to and including Motec v1.0.1. The issue happened in both cases. The crash almost always happens when I click the drive button to go out on track, about 90% of the time. About 10% of the time it crashes when I click on exit back to pits from the escape menu while out on track. AMS will CTD on average around once every 3 or 4 times I click on the drive button. The last time it happened, it happened the very first time I clicked drive. I wonder if it's got to do with memory? I accelerated my 22 car session to around 30 mins into the session the very last time and the instant I hit drive to go do my first laps, bam, CTD. Again, though, there's no warning about low memory like the DataAcquisitionPlugin thread in racedepartment said AMS would give if memory was running low. Can anyone else with the DataAcquisitionPlugin/Motec try the following race session to see if it's just me?: - race weekend - circuit = Salvador - vehicle = F301 - AI = 11x F301, 10x F309 - time accel = 3x - track progress = off - track condition = heavy - sessions = all 4 practice session + quali + warmup + 1 race - race based on distance @ 30 km Go in and out a bunch of times. Accelerate time for around 30 virtual minutes then click drive, then escape back to pits, and repeat a few times maybe while watching some cars or on TV cam sometimes before hitting drive (just to mix things up). I am going to remove and disable the DataAcquisitionPlugin plugin and do a longer session just to make sure the problem really is connected to the DataAcquisitionPlugin.
