[1900.20] Object reference not set to an instance of an object. Again.

Post by MauriceB »

Well it's back. I was playing CMO earlier today just fine and now anytime I try and load (or edit) a scenario I get "Object reference not set to an instance of an object."

- Running in Administrator Mode
- Did a verify integrity of game files in Steam
- Rebooted PC

Attached is the ExceptionLog

Look for software that may interfere with CMO.

So got this error trying to load a scenario about 20 times in a row then thought I'd try something different and do a "Create New Scenario" then immediately did a File | Start Menu | Start New Game and I was able to load a Scenario just fine. So I have no idea now what's going on, but it seems o be working again (for now?)

Hmm I also have Razer Synapse and it has a process listener to switch profiles if command.exe is running. Might be on to something here, will do further testing.

Nah, nothing works consistently. I've tried disabling software, verifying game files, rebooting at least 30 times and maybe once i was able to load a scenario over the last 2 days.

Here's my ExceptionLogs over the last 2 days.

If it can be posted, in the task manager what is the list of software that start up with windows?

Have you disabled what is not essential, restarted the PC, and still happens?
