Upon entering my account information on the launcher, I press the go button but nothing happens.

The should be a area where you could see the total number of used pieces, so when you are aiming for a vehicle with <30 / <20 parts you don't have to wait until you have ended a race.

whenever i make a car and change the  power and key assaignments on individual rockets and try it out i can't save that setting  when i have to go back to edit the car or level the settings on keybinds and power of the rockets are reset

i have tried a little bit.
Saving is no problem as long as i make new vehicles.
but if i take a existing save i can load it and drive it
and edit it but there is no chance to save it again. (sace screen corrupt)
i can make a video for you if this helps ?

i am trying to buy the game, i fill in all fields and it still says Form incomplete! when i click paypal
