Thanks for the help, but panic is exactly what I did. lol. What I tried last night was the extended database repair in TANE, just the way you have listed, and that's what left me with the 100's of faulty assets, for whatever reason, is beyond my comprehension. It did take a while, around 2.50 hrs for the repair to run. Afterwards I was stunned when I saw just how many errors were there, on payware, and built-in assets as well. I initially tried the 'view errors and warnings,' which had worked for me on TS12, and a few of them did go away, but the majority of them stayed. I eventually tried 'revert to original,' several item at a time, and that took care of the majority, eventually. I stayed up a bit longer editing a few of the individual items left as faulty, mostly replacing 'obsolete' coronas, that worked 3 hrs earlier, prior to the database repair, but now were faulty for whatever reason. Fortunately, only a few remain to be dealt with after work this evening, then I can see if the P&B that I want to operate so badly, that was the catalyst for this whole unfortunate adventure, is now working correctly. In summation, an Extended Database Repair, NOT RECOMMENDED, at least for someone with my limited ability. Does anyone know why the extended repair generates so many faulty dependencies, that up to the point of running the extended repair, work just fine in the Sim? Thanks again for the advice..........................Ryan
