Wu showing 12K hr's to complete

Need more info... was this WU 2013474? If so, it looks like you aborted it, which is what I would have recommended, and no further action is needed. If not, if it's a higher WU number, then it's possible you have an entire bad "chunk" of WUs, and will wind up aborting each of them as the estimated time gets absurd - or, something has gone wrong with your computer. I say this because 2013474 was bad, and 2013476 and 77 are "in progress" on your PC. (2013473 however looks good...)

There isn't a method to report "bad" WUs, but they are detected by the validator after a few (I believe 5?) people return them with errors - it will not continue to be sent out forever trying to get a good result.

You are the first to receive this "block", it's still "unsent" to anyone else, so we really can't tell you anything specific until others have had a chance to crunch it.

There aren't any valid WUs coming from Einstein that would take more than a couple of days to crunch on your computer. I would HOPE that if you had let this one continue to crunch, the software would eventually have hit an unrecoverable error and aborted it on it's own - I shudder to think that there might be computers out there "unwatched", that are working on the same bad WU for months and months...
