Jar won't run after using profiler

I have an executable jar file in my dist directory, it used to run when I double click it, but after I tried the Profiler 5.5, it can't run any more, it says "Can't find main class", can someone tell me what happened ? And how to fix it ?Frank

I figured out why, it had nothing to do with profiler, I forgot to include other jars for it to run.But I hope there is a button in Netbeans to get back to the state before using the profile, automatically recover build files ...Frank
