Ah, yes, temporary Flash files are being blocked for some reason.
It's possible that you have that allowed, but only up to a certain size - worth checking in that Flashplayer options menu if you can increase the file space allowed.
It's also possible that some other application is interfering, maybe an antivirus, Windows settings, or PC-cleaning utility is blocking all Flash files, in which case it may be tricky to figure out what exactly the problem is. Sorry about that.
