Share Buttons garbled

I was having problems with the recommended content showing up, so I tried to remove Shareaholic and install it again. Now that it’s installed again, the buttons are looking all garbled.

If I change them to the rectangular images it works fine, but the square ones (which I prefer) are looking messed up.

Any help would be appreciated.
