Issue Description:
When attempting to join an online game hosted on another computer, Nerf ArenaBlast crashes. Usually, an error window complaining about something called UnChan.cpp will pop up.
Solution #1 - Make Sure You Are Updated:
The main cause of this crash is almost always a file version mismatch between the client (you) and the server (host). If you don't have any special file arrangements made with the server host, make sure you've installed the latest Community Pack and updated using the Updater. Since updates are released generally bi-monthly, you should double-check for updates even if you updated recently.
You may have also accidentally changed or modified a file through NerfEd. You can re-install the Community Pack and re-update, and this will generally fix the issue.
Solution #2 - Make Sure the Server Is Updated:
As I mentioned above, the cause is usually file version mismatch, but it could be the server that is out of date. If you do not have access to the server you may wish to notify the server runner that they are not up to date or otherwise mismatched. If you are the server runner, you can repeat the above steps. Make sure your server is not running while updating!
Solution #3 - Resolve a Different File Mismatch:
If you and the server host have a special file arrangement (testing a BETA update, using an old version of a file) make sure you are up to date before you install any needed files. Though this is a rare case, you might see BETA servers up during developer testing of new features that unless invited, you may be unable to join.
