The EOdb error can be caused by a few situations. The first case occurs when reports are taken in a newer version of the software, and then viewed in an older version. The second case happens when reports are viewed without having any machines in the Machine List. For example, the error appears if a user takes reports, deletes the machine, and then tries to the view the data.
The third case is more complex. Here is an example scenario that could cause the error:
The new version will allow you to view Samsung and Sharp reports, but not CRS reports. Download and install a build created for the CRS to view the CRS reports.
