The first time you open the game your best times will be set to 0. This bug will be fixed eventually but I'm honestly tired of save data at the moment. So to fix the best times go into your save file and copy and paste this text into the save file:

TSSTimeRemaining=300

TSSHMTimeRemaining=300

Make sure to not change any thing else in the save file as it could break some stuff.

In case you don't know how to excess the save file here is how.

1. press windows key and type run then enter

2. type %appdata% into the popup. This opens a folder.

3. go to MMFApplications and find the file named CCNSaveData.

4. Open this file in a notepad document and paste the text above into the file then save.

5. Open the game and your best times will equal 300.

Sorry for this bug I'll try and fix it when I feel like doing save data again.
