As I've been posting about for the past week and a half, the Speeder database has been migrated to Cloudflare, which is extremely fast and also allows for much easier distribution of addresses. This means that you need to use the latest version of Speeder and Launcher if you have not updated within the past week. If you have updated within the past week, you should be all set.
The latest version of Launcher can always be found here: Downloads - Speeder Cheats
The latest version of Speeder (both .exe and .dll) can be found in your MEGA folder. Your MEGA folder can be accessed by clicking the "MEGA Folder" button in Launcher. Download and replace the old Speeder with the new, and you will be all set. You do not need to replace anything else.
