Access problem to my database *.frm files

Hello,

I'm a beginner with pentaho.

Even if my connection to my database works, when I try to do a new report with my database i got this message :

10:16:05,340 ERROR [SqlMetadataQueryExec] SqlMetadataQueryExec.ERROR_0002 - Query execution failed: Can't find file: '.\@0022pointage@0022\@0022seances@0022.frm' (errno: 22 - Invalid argument)


Resolved !
I must declare datasource in PUC and NOT IN PAC
