Not sure if this is a bug or I just ????ed up, but this is what happened. In the campaign I started doing the races, I did the first few and bought some upgrades with the tokens. My problem is I did not buy ROCKETS and the only races available to me require rockets. I cannot earn tokens from the previous races I completed and have no way of getting tokens to buy the ROCKETS so how do I advance and unlock the other races? Is there a work around for this, do more maps get added as you play the campaign?

Any help is appreciated. I personally assumed you could run races multiple times for rewards, but sadly that's not the case.
