I am not sure what CRC stands for, but I will mention that, after viewing the log files, the AC uses an online source to detect some things, and I have no clue what exactly the site is used for. It's the one with htt://IP NUMBER LINK. It may not be significant at all.
And to the person who said that a computer restart is the only way to start AVA back up, is not 100% true. I can start it up again after getting a 3rd-party-error and be fine by deleting the log files and xm.exe from the XIGNCODE folder in binaries (and the file above that... cant remember the name for that particular file... not on my computer atm.) When ava starts up, it will redownload that exe file and the other one I mentioned, though it does not always work on the first try, it may take 2-3 more tries to actually start AVA without getting errors even when no other apps are running.
