Running the SQL tuning and receiving error "failed to retrieve query plan" (4283486)

When executing a query in the SQL Tuning (within Database Expert 15.0) connected to an ASE 15.0.2 server, the following error occurs: 'failed to retrieve query plan' .

Works against ASE 12.5.1, 15.0.1 but not 15.0.2.

The tables exist, but it said 'Table does not exist'
Not sure if the "Failed to retrieve query plan" is related to ASE 15.0.2.

Problem is on Sybase ASE version 15.0.2.

WORKAROUND:
None

STATUS:
Issue fixed in version  3.0.0. The latest version of  Quest SQL Optimizer for Sybase  can be downloaded here
