HOLY BANANACOW YES! I have no idea why or how but it suddenly started working! Thank you all for trying to help me, now I got several projects to check out!
I have already told you that changing browsers doesn't work. Now, this Javascript thing caught my attention. You see, I'm using a Mac computer and as far as I know they don't have Java. Could this be the issue? Then again, I've tried regular Windows computers to no avail.
