ECLIPSE: cvs [update aborted]: could not find desired version



Hi
Whenever I try to do a cvs update in Eclipse (V 3.1.1) I get the
following error:
!MESSAGE web: cvs [update aborted]: could not find desired version 1.5
in /home/smitherington/cvs_repos/apc/web/finfo.jsp,v

Does anyone have any ideas on how to fix or get around this so that I
can update my files and cvs files?


Thanks

Kay
