Can't log in now. Error: Could not copy graphics.jar to graphics.jar.bak

[Amadee 1,543]

-Got an update while logging in a couple hours ago. No problems except tomato crop graphic. 

-After doing a few things like farming and collecting sprouts, I clicked on my cookbook and the screen went black.

-Alt tabbed out and there was a Java message that it was blocking for some reason. I can't find a log for it.

-Clicked "do not block."

-Restarted game and it gets to 100% and then hangs with the message that it "Could not copy graphics.jar to graphics.jar.bak"

-Tried 4 times now and same thing happens every time.

 

-Clicked "show error log" and got the following:
