I have found several issues with CSV file joined to point features in 10.1 (and SP1)...
The join now changes the syntax of the joined columns to <join_table>.<column_name> in the label expressions... All prior label experssions no longer work. The label expressions (VBScript) do no seem to work either.
The Label "Verify" hoses the software and does not return, causing abnormal exit.
In one case, "Open Attributes" on the joined feature, also caused the software to hose up.
If you frequently use CSV files in ArcMAP, I would not upgrade.
The work around is to save the CSV as XLSX, but the XLSX join also changes the syntax (same as above) for joined tables and columns causing extra work in label expressions.
