Make a note of when the runtime error pops up. The most common fix for this is to delete the .ini file.
If your computer operating system language is not English-US by default, please review the below computer configuration document.
See: International Computer Configuration (PDF)
Delete INI:
1) First, open a folder and (depending on the version of Windows) there will be either “Organize” in the top left of the folder, or “View” in the toolbar.
a. If in Organize, you will see an option for “Folder and search options” open this and go to step 2.
b. If in View, then you will select “Folder Options”.
2) Find the Hidden Files and Folders category and change the value from don’t show, to show hidden files and folders, and hit OK.
3) Delete the .ini, go to C:/Program Data/ShopBot/ShopBot 3 (This is not on XP) and delete the file called “shopbot” that is the configuration settings file. If on XP, it is in C:/Program Files/ShopBot/ShopBot 3. Once deleted, restart the shopbot software.
If this does not work, follow the software uninstall/reinstall procedure on pages 3-5 of this document: Uninstall and Reinstall SB3
