Did you try using another web browser to open them? (Which web browser are you using? Internet Explorer? Mozilla Firefox? Google Chrome? Apple Safari? Opera or something else?) Also did you try right-clicking on the links and selecting “Save link as…” to download the file, and then try opening it from there?
I would try that. I remember having problems opening the VEX .PDF files last year using Google Chrome, (I think I did end up getting them working opening them in Mozilla Firefox) but by saving them I was always able to view them, so I would either try Mozilla Firefox or try saving them.
Well I know that your question has kinda been answered, but let me just clarify. The width of the goal from the interior of the goal is about 7.824 inches, and the width from exterior of the goal( the black part) is about 10.43 inches, as said by Vex Mundi.
