Well, I am trying to be helpful. I already said that Calibre runs fine on my end and that I informed Soluto that the problem is obviously on their end. I updated Calibre and I still have the same "crash" reported. I just thought I would post it in case anyone else is having the same event error. Or in case anyone wanted to look at my log files. Or whatever. Have a great day.
See:
Calibre Crashes When Converting. The "solution" was to not use Soluto.
That's just unacceptable to me. It shouldn't be either/or. They should be able to work together. So I informed the company and I just thought I would post over here. I didn't realize anyone else had had the same problem until I had already posted my "crash".
