I just re read your OP and you did say that you copied from your browser address bar, but it said "invalid."
Did you check if there were two "
http://"
For some reason, when you are posting links on TER, they already have the "
http://" in place, so if you just copy and paste, you end up with a double "
http://" You need to delete one of them. I just thought that might be your problem. Good luck.
