Has anyone recently experienced issues where access to the Workgroup vault and checked out parts are not behaving correctly?

This morning I had two issues: 1) Items checked out of the vault were suppressed when the assembly was opened and could not be resolved even if the items were open in memory.

2) One user could not get access to check some parts out of the vault. She received a message that she did not have read access to them, but did to the assembly that was located in the same area of the vault. Also, a check of permissions showed that she did have read access to the files.

My company has recently delayed in keeping up its maintenance fees until next year. Could this have something to do with it? I would not have thought so, but now wonder about it.
