getting errors

I hope I'm posting correctly.
When i try to run the updater I get this error.
Unknown Error: System.Drawing
at System.Drawing.Image.FromFile(String filename, Boolean useEmbeddedColorManagement)

also tells me only 1 instance can be run at a time. I've removed the program and reinstalled it but with same results. Also I had this problem before I downloaded the newer version just a few minutes ago.
