Hi Jack , i did CRRL+F5 and nothing seemed to happen,i still can not do the practice
i don´t know how i can upload a picture from my screen and you could see that i´m having this problem...please helppp i lost already some points last race with a pit problem that i already reported and i can not lose more points :) if not the 1st in my league will have more advantage and maybe the 3 one could be passing me :(....Hope Jack you can underestand me what i trying to explain you,due my english writting is a bit crap :)

Could you tell us what browser and what operating system you are using?  Can you try on a different browser or a different computer to test to see where the problem lies?  Thanks.

Thanks Andrew for your answer,
I´m using windows explorer and my operating system is windows 7,i tried with firefox and it seems to work,i will do my practice today with firefox but i don´t underestand why i´m having now problems after 10-11 races,anyhow thanks for your help

As Jack said try clearing your browser cache (in internet explorer), that\'s probably why it worked in firefox (as you haven\'t used it in firefox beforehand). 

I have the same Problem. I use Firefox 9.0.1. in Windows XP and i cleared the cache now... the problem remains!
Please help me because i have bad results wihout Practice since last 4 Races.

I did the same with IE (clearing the cache) and now it works with Internet Explorer. But with Firefox i still have the problem. Tomorrow a give you a screenshot.
