Q: Why when me and my friend change tires to the same pack (ex. Soft - Hard) we got mistmatch?
A: F1 Challenge '99-'02 is also checking the date of edited file, so that's why there's mistmatch, even tho files are the same.
Q: When the next update will be available to download?
A: When it's done.
Q: What data is being send and when?
A: Windows version, GamePT version and when program was launched. It's enabled by default and GamePT is sending it every time when you launch the program, but you can easily disable it in the settings.
