You cannot run v5.0 w/o patches!  (If fact, whenever you upgrade I 
recommend you contact Veritas support or at least go to their website).

V5.0 has a required patch.  In addition, 3 maintenance packs have come 
out. 

My guess is that you've probably been bit by the corruption the patch 
would have avoided, so you must go through the procedure to clear that 
up, then apply MP3.  It's all there at the Veritas support site  (and 
the problems of base v5.0 are also here in the archives of this mailing 
list).

cheers, wayne
