While playing, after a time of 15-30 minutes I will get "No Message Received for X Seconds..." and at the very moment it pops up a Windows Error Message pops up saying:
"DayZ.exe - Drive Not Ready"
"The Drive is not ready for use; its door may be open. Please check drive A: and make sure that a disk is inserted and that the drive door is closed"
(Drive A: being the floppy drive, I find it kind of hilarious)
At first error gives you the option to 'cancel,' or 'try again.' Trying again has a possibility of giving you an additional 5-10 mins of gameplay, cancelling has a high probability of simply getting you stuck on "No MSG rcvd". After first pass through on error message, it will pop up again with 'Cancel,' 'Try Again,' and 'Continue'.
Upon this error, there's a low chance you'll click try again and get 5-10 mins of gameplay, and every other button seems to be certain disconnection from the server.
(It's all so very strange, and the problem started last night on experimental as well)
