Bad Build?

I had a number of students tonight struggle after installing the latest update that was deployed (XXXX.006?).  In short, after updating to the latest build/release, they were not unable to open up RapidMiner and were not able to participate in tonight's lecture.  Simply, the startup process failed and they couldn't do anything to get it running.  Even safe mode was an issue.

Is there a supported resolution to this problem?
