Hi, recently upgraded from metastock 7.2 to 9.0

after imported all formulas, expert and charts, actually when I open my old securities data with the new version i got the error in the subject followed by " insufficient data sources to fullfill price data request" after this the charts is opened with all my old trendlines etc., but with another message in the center "waiting for data, press 'Esc' to cancel.

At this point if I click Esc the chart colses itself, but if I change the date's range everything goes ok.

I tried some workaroud such as:

deleting the smartchart's (its folder included and not included) in the securities data folder;

copying securities trough the downloader application.

Well nothing worked, the error message was always there wathever i did.

Anyone knows how can I fix this? Did I get damaged files o what else?

Note that it happens not with all securities also if setted in the same folder.

Thanks In Advance for any answer
