Invalid SQL when I try a play

[morris2003]

I've upgrade from 1.1.1 to 2.0.0.
When I try a play:

Invalid SQL:
SELECT MAX(score) AS personalbest, MIN(score) AS personalbestr, gameid FROM v_arcade_sessions AS arcade_sessions WHERE gameid=100 AND userid=1 AND valid=1 GROUP BY gameid;

MySQL Error   : Table 'forum.v_arcade_sessions' doesn't exist
Error Number  : 1146

but everything work fine.
