SAP b1 integration error

Hi Guys,

If i open the SAP Business One Event Monitor( SAP 9.0 PL 15) , I get this error :

XCE045 IPO-Step not known: XCE205 resource is not known /vP.0010000100.in_BEAE/com.sap.b1i.vplatform.runtime/INB_B1_EVNT_ASYN_EVT/INB_B1_EVNT_ASYN_EVT.ipo/proc

Any ideas?

Thanks!

Regards,
Darius
