If you receive an SQL Error referring to stock.log which is preventing you from using StockMarket Plus it generally means that a process didn’t correctly stop the last time the software was run, or some older files were leftover prior to an installation of a new version.
To fix this error, browse to the location of the database that you use to run the software, and locate and delete the stock.log file.
Unless you run a multi-database setup the file will be in the default location which is C:\Program Files (x86)\StockMarketPlus (V14 or earlier) or C:\StockMarket Plus (V15 or more recent)
If you use a multi-database setup, then the stock.log file will appear in the same location as your stock.db file that you load, e.g. if your stock.db file loads from C:\users, then your stock.log file will also be in C:\users, then your stock.log file will also be in C:\users
