6.4 should be able to handle raster maps from 4.3; I don't know
whether anything changed between 4.1 and 4.3. Vector data may be a
different matter; there were substantial changes to the vector code
between 5.3 and 6.0; if you have problems specifically with vector
data, try 5.4.1.

Is that a transcription error? It should be PERMANENT, not PERNAMENT.
The "is not a valid mapset" error normally indicates that the
directory lacks a WIND file. Copying the DEFAULT_WIND file (if it
exists) to WIND should suffice.
