Regarding the same error message mentioned above ... I'm a 2nd level computer support person/programmer and would like to buy the engineer license to use for my client's systems. However, I don't have much faith in the product if you can't fix a simple bug like bypassing volume checks on empty card reader slots. I was using the trial version and had to click on "cancel" twelve times for each item I wanted to add to the OSD, Gadget, LCD or Sensor panels. It is clearly caused by my four empty card-reader slots. This is happening because your programmers have put the volume (or drive) check at the entry to the panel setup screens instead of at the addition of a specific drive item where it belongs. That way it would only popup an error if you were trying to add a drive that was actually empty. I'm waiting to see if this can be fixed before I spend $149. I'm sure a lot of other users have card readers and the same issue but are too complacent to bother trying to get a fix. It should be fairly simple to bypass USB drive types which is how card-readers are attached. Or just move the calls in the code to check the volume/drive when a user is adding a drive to a panel. So where do you stand on this issue???
