We are currently aware of the site experiencing technical issues and looking into it. We have a larger discussion on this in the following thread here:
I just bought NCAA Football 14 recently after seeing it on YouTube. A lot of YouTubers are making teams in teambuilder and so i decided to make a team for myself.

This is a known issue.
Please monitor the following thread, when we have news on this it will be posted in that thread:
