Sharepoint foundation search refresh job not starting

Hi all,

I have a question which i cannot figure out by myself.

I took over an old Sharepoint and got it working again, changed bindings, etc.

Searching now works but the Sharepoint foundation search refresh just won't start. 

It was set at default 5 min. and i found that the Search service V4 was disabled. i enabled it en retried. 

but no luck. i tried several other smaller fixes but it looks like everything is in the right place.

if i check the job timer status the search refresh can't even be seen.

anyone got an idea?
