I am getting this warning for all the libraries in virtuoso (IC616)

Warning: ddiAddLibtoOA: Can't access library'Library name" at path "path" in OA 2.2. OA Exception is: Syntax error in .oalib file of the library.

and can't access cells in user defined libraries also.

Even newly created libraries also show this warning and my design under the library disappear after some time
