Make sure you're using the Newest release of the Editor.
The Jackpot Jacky option is in the 4th tab down, Misc. tab.
Jackpot outcomes are in the drop-down list. You select which jackpot you want to get, then click the ACTIVATE button just above the drop-down list.
Along with using the "golden key" option of the Trainer, which also makes the slot machines free, is by far the best idea for hitting it big Vegas-style!
All I see in the Misc. Tab is:
Change Mission Timer
Change Shop Timer
Maybe you could put the version number on them from now on just to make it a little less confusing. Seems to work fine now, thanks.
The EDITOR creates a .tmp file and a CH.dll file, those should be removed. They should safely be removable as long as the editor is not active.
The TRAINER creates a CH.dll, an Options file, a help file and about 4 .ogg files. Those can also be removed safely.
When I download a new file, I rename it with the Posted/Upload date, and do so with the exe as well. Such as "CH-BL2-EDITOR (01-Oct-2012).exe". This has no affect on trainer authentication as far as I've seen. Then make a new shortcut to your desktop with the newly downloaded and renamed file.
