Sounds like a server side issue with the primary archive. Check out this KB article: KB01181.
Do you have access to the PI Server? Take a look at the PI message logs on the PI Server as well as the primary archive online.
Jason on tech support solved this by registering the archive - running the command: piartool -ar "C:\Program Files\PI\arc\2012R2-DEV_2017-03-21_00-00-00.arc"
Hope this help someone with the same problem in future
