Forza 6 (not able to see any tracks or cars except qualifying race) - help needed

Sir ,

I recently purchased forza 6 through Amazon. When I put the CD and start playing this is what it happens .

  1. After a small video about racing the Forza6 starts
  2. After it started it gives a race to take with a high end car .
  3. atfer completing that race it is asking me to enter qualifying race .
  4. Till this moment am able to play only the qualifying race only .
  5. I could not see any other tracks or car .
  6. The cars which are displayed in this qualifying race or low end and using that it is impossible to complete even within 15

Please guide me how can I see more circuits racks and more cars .
Am doing something wrong .

I was having Forza 6 demo sometime before and now i have installed Forza 6 game .
Please let know is that having demo version and installing full version had caused this problem .

Need help or assistance .

you need to complete the first few ( i think 3 ) races before more of the game opens up

maybe change your settings so they are easier for you to beat
