DTPO Database won't open after upgrade to version 2.8.6

After upgrading to ver 2.8.6, I find I cannot open my database (only have 1). DTPO boots to a blank screen, I then click on FILE>OPEN RECENT>DATABASE but nothing opens. Just before the upgrade from 2.8.5, I synced some files between DTPO and DTTG. Prior to the upgrade program seemed to be running as expected. Using a MBP and Yosemite 10.10.4. Available HD space is > 500GB.

I’m in the middle of a Real Estate Transaction and would like to have access as soon as possible.

Thanks,

Bill
