What missions does this happen in? Many crash reports seem to be from Wasteland players, which is not an A3 issue. You have provided very little information.

Sorry I have not been playing any of the modded servers for this reason. Sorry if I didn't give sufficient info, I am new to ARMA and the servers can be a bit confusing. This has happened coop maps escape from the island or something like that. Is there a way for me to find "vanilla" servers so I can be a more effective tester?!?

Thank you for your fast reply!

We need dxdiag and files from this folder for solve your problem. C:\Users\<Name>\AppData\Local\Arma 3 Alpha\

Can you upload somewhere in winrar package please?
When package will be smaller than 5,000k, so you can attach here. Thank you.

I have experienced the same constant crashing with the development build while playing multiplayer, i just now played on a HOLD map, crashing just after running a few hundred meters.

Uploaded my DxDiag on this site and here is a link to my ArmA 3 Alpha folder.

Sorry haven't been able to play for a bit. Played today and had the same kind of crash. Just seems to hang then I need to ctrl+alt+del out to task manager and then it tells me the program has stopped working.

I went to make the rar crash file you requested but it is more like 8,000k.

We have distributed the new stable version which includes many MP fixes, so please can you tell us if your game is still crashing?

It seems to be fixed.. closing

Mass close.
