MX Simulator

Just recently I tried to sign up for the mxsemf nationals on my pc and it wouldn't open the link to the amateur nationals race or any other race series. I don't know what's going on because I just raced the sx season and didn't have any problems with that. It also does the same thing on mxslobby. I get on their page and it doesn't even pull up the upcoming races but when I get on my phone it let's me click on the link to all the races on each website...
Please let me know if anyone knows anything that might be helpful!

Thanks!
