BJS should not be inside the Symbol Database (assuming the symbol database has been updated), but it is possible that you may have an old symbol in a Local Data folder (We do not clean symbols out of a person's local data folders).

We update our symbol database files once per month, so it is certainly possible that a symbol could change shortly after we build the symbol database, and it will not be reflected in the symbol database for about a month.

However, a symbol not being in the symbol database does not prevent you from accessing the data. You can manually create a security using File-->New-->Security and just type in the correct symbol. You can also edit a symbol (in the case of a symbol change) by opening the security file in The DownLoader (File-->Open, browse to the data folder and open the security, then change the symbol at the top of the data sheet). You can also manually add or edit a symbol that is in the symbol database (i.e. File-->Open-->Reuters DataLink, then click Tools-->New Symbol, or you can type the old symbol onto the symbol field, then right-click on the old symbol and click Properties and change the symbol).
