I took the advice of WGT's moderators and updated my Flash. It reset my settings to "automatically update". Now I have version 14.0.0.145 on Chrome.
I tried to clear my cache tonight from the game client (right click, select global settings). When I did that, it loaded the help menu.
So ... how do you clear the cache with that version? I do have a bit of an erratic meter right now ... I know it will only get worse!
(are you out there Scott?)
