generally when database has been updated newer version of sql server server trying attach from. instance if database upgraded sql server 2005 sql server 2008, no longer able open database on sql server 2005.

the "downgrade path not supported" message implies can't open newer database on older sql server version.

suggestions:

or

open database on server newer version of sql server, script out entire database , reload server.

either of these should working your.
