After upgrading to Mohave 10.16, my Promise Utility would not run.  I upgraded to the latest version, and it won't recognise the two R2 unit that I have hooked up.  They both show up on the desktop normally, but the utility doesn't see them.  Because of this I can't upgrade the firmware on these units. Does nayone else have this problem?  I tried to open a support request, but got no response from Promise.  Any suggestions would be appreciated.
