Confirm you have setup your maintenance plan as per our reccommendations then run it again. If the size of your LDF file is not reduced after running the maintenance plan a new LDG file may need to be created.
One way to do this is to detach the database and then delete the LDF file. When re-attaching the database, MS SQL should give you the option to create a new LDF file.
NOTE: When doing this we highly recommend that you first stop the versaSRS Services then make sure that you backup the .mdb and .ldf files in case there is a problem.
Once the database is re-attached, verify the data, by performing a count of the number of records in the following tables: tbl_Calls, tbl_CallAudit and tbl_CallAuditAttach.
