BPM doesn´t start process neither can see the process flow

Hi everybody

After I deploy BPM applications I can´t start those or see the process flow; I go to nwa>Configuration>Processes and Tasks>Process Repository, There I select my component and I try to start the process flow whit the Start Process button I get next error: Details required to start this application not available, see log C000AC13A2460BF400000003004501CA

And when I try to see the Process Flow with the Process Flow button I get this other error: Error while loading process definition. Contact your system administrator.}

I hope you can help me…..thank you
