How do you troubleshoot a "missing" Participant

I have multiple participants already but am hitting an issue with a new one, in that it isn't showing up in the list of available participants on a WorkItemSave action.  However, I am unable to find any indication in ANY log (that I can find) that would indicate what the issue is.

I have already:
1) did a requestReset of the server
2) taken down and restarted my Eclipse client.  In fact, I actually installed a NEW eclipse client on the same machine as the server and it also doesn't show up as available there (i did this to ensure no weird client caching of the project area)
3) double-checked the name of my update site URL and the FeatureID in the provision_profiles .ini file

When I do all of this, then restart the server, it starts.  However, when I go to Operational Behaviors, the participant isnt' shown as available.  I see nothing in the ccm.log file that would indicate any issue loading this (there are multple errors about migration tasks that couldn't succeed which I don't really understand since this was a brand new machine that never had RTC on it before).

How would one go about figuring out what is wrong?  For example, did it read my CreateVerification.ini file and attempt to find the update site?  Did it not find the update site? Did it not find the Feature ID? For some reason did my feature not get built properly so it can't find the right things as it loads?   Could I be missing a dependency? Would it fail on a dependency here, or wait until the first time the plugin was actually called within the scope of a WorKItemSave?

I believe I have double-checked everything and am quite stuck :-(
