I use google chrome and firefox newest version the whole time. I tried to view all the videos, then this error only happens to F1, F2, F3 while i still could watch from F4 forward.

Please take a look at this picture https://img835.imageshack.us/img835/3011/f1acca.jpg

What a pity that i could not watch the lecture of F1, F2, F3 🙁
