Reboot your computer. Once the computer has come back up, DO NOT try to open Data Manager. Open Windows Explorer, locate the c:\wintes32 folder. Locate the tdata folder. Delete the files master.adf and master.ndx. Once those files are deleted, open Data Manager, say Yes when asked to Rebuild.
This should clear up the problem.
You can get updated list files from www.aiqsystems.com/lists.htm.
Open Data Manager, click on Utilities, choose Rebuild Master Ticker List.
When I update I keep getting a message “limit exceeded”, and data will not update, how do I correct this?
Open Data Manager, click on Utilities, choose Delete Non Trading Tickers.
