I am trying to upload a 1.2 G avi video file onto youtube. The youtube upload progress bar goes all the way to 100% and then freezes. About 20 min. later an error message pops up and says, "Upload failed, Unknown error" I tried using youtube's advanced uploader but youtube says that java isnt installed on my computer or java isnt activated. I download the latest version from the java website but I cant even find where it is on my computer. Its not under programs. When I tried to download it again the java site recognizes that it is already on my computer. I cant find where it is though. I am using Dell latitude with win xp and a sprint air card for internet connecting. Any ideas as to why I cant upload on youtube?
