It looks like you just exceeded the number of downloads allowed.
Even if you can’t download more documents now, you can still enjoy watching all the videos. Those are still accessible to you. In addition, there is a lot more in the Campus.
Then, just come back in a week to download more. After all, it will give you a time to really pick and choose which documents you really need!
So, for the time being, get yourself snack, relax and enjoy a walk around the Campus!
