DatDocsTbl: Type mismatch for field 'DOCUMENT_NAME', expecting: String actual: Memo

The error message itself is related to a version mismatch.

You mentioned that all PCs work well except for one.

We suspect that this one PC does not point to the exact same installation file on the server. Maybe its mapped drive points to an old location, etc. Verify that you visit the exact same file/path as others. Check the RangerMSP.exe file date and compare it with the one you see from all other PCs where it is working as expected. Etc.
