Unable to open master database due to the following database access error

Hello.

I have this bugging issue, which appear in assemblies, when there are standard components created in SW library.

Next time I open the assembly, error table appears "Unable to open master database due to the following database access error", although the component is in place.

Please help get rid of these messages, as it becomes very annoying to work, when there are a lot of standard components in assembly.
