ArgumentError: Error #2082: Connect failed because the object is already connected.
To quote Seth Hodgson at Adobe:
That should be an intermittent problem. If the Flash Player is force quite (due to a crash, force quiting your browser in Windows Task Manager, or possibly stopping a debug session in FlexBuilder) a LocalConnection may be orphaned in shared memory. When this happens, if you restart your app and it attempts to reconnect its LocalConnection it will fail.
Try making sure all Player instances are shut down which will clean up the orphaned LocalConnection and worst case, restart. There’s a bug logged for this and you won’t hit it during normal operation.
Restarting the computer fixed this problem. Some have stated restarting the browser fixed it.
As reported by rock star reporter and coder Andriy Panas, Peter DeHaan from Adobe, has suggested to wrap up the call to _lcFromFlash.connect routine into try…catch.. block as mentioned in this thread http://www.nabble.com/Workaround-for-Error–2082-tf4209682.html#a11974844.
