Error "given key not present in dictionary

[willmoodom]

What does this mean? I just updated to the latest offerings. Everything has been downloaded and installed twice with hopes of clearing this up. No go.At the end of every build I get this message. Also, something new to the software? what is the modemlink? during the build, I'm given the choice to overwrite multiple files related to modemlink. I've tried yes and no, thinking that was why i got the error at the end. No change. First things first though. Can anyone shed some light on the error issue?
