I can’t watch any video when I click on it. The video area is black and I can’t study. It’s so frustrating!
Help! !
I am using win7-64-bit system, and I have a 5-year-old HP laptop with a dedicated graphics card (although it is very crappy). What is the reason? ?
. . . . .
I really can’t come up with these 100 words, I’m so sad. . . . .
