Missing ticker entries

I Now have a ticket list that is 1/2 "0"s and the first half of the former list if stocks.
I use TC2000 data import and do not use AmiQuote. I have searched here without finding what my problem is. Any juggestion or reference would be appreciated.
Thanks in advance
Thanks !!!
BTW: My programming skills are poor compared with the Masters Of Code who populate the site. I once told invesstor friends that "AMI can do more with little code than on competitors" (Just look at TASC magazine)
Now I say "Magic takes but a few lines more".
