Hi, there is no need to try another browser. It is in fact a flash player issue.
First, clear all your browser history.
Second, click this link to access Macromedia
Third, on the left hand side locate the "website storage settings panel" and delete all sites.
And finally, slide the memory storage bar to the unlimited position. Once completed, close this page.
This should solve your issue. This will happen when the flash memory gets close to maximum capacity.
Hope this helps, LC
