It happens sometimes, just wait a few hours and it fixes.

Hey khemist I had the same problem a while ago and this is how I fixed it:

Im not a PC technician so this may be incorrect Im just sharing how I fixed my issue so don't flame me plz ppl.

open up regedit, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA
right click on the ArmA 2 OA folder and hit permissions, then hit advanced, then remove any profiles in the list that it lets you. (the important ones are greyed out)
Hit apply and try darky again.
