everytime i trying open the key it said offline my data internet is strong enough to play the game i guess..can u fix this

also after buy a new part of performance i cant see when it arrive...it will be 2200h 300m 100s something like that

I have a corvette from tier 3 and i have it full tunning with a lot of fusion parts and 4 level 6 parts, en it does race so fast. I made 9.400s in a 1/4 mile. But idk why when i race in live race, with others players, is so hard to win, the made 9.3some or lesser, and i remember when my hellcat wasn't tunned or the corvette wasn't tunned at this level, people wo won me only made 10.3some, and I wanna ask if the game have any soecial funcion to tie the races, making slowest cars go fasters...
