3.301 issue

[WDEWDAD7]

I have been trying to download the 3.301 upgrade. I have saved to discs and hard drive. It will take the set up, but will not complete the upgrade. As you can see by your records, I have used 5 download to try to complete this. Do I need to purchase the cd-rom to complete my upgrade? I also noticed today, 2/12/06 that it says the mtu store is down. Is it still down? and is this why I can't download my upgrade? I have un-installed and re-installed 3.3 several times, to no avail, as far as the uipgrade goes. Am I supposed to un-install 3.3 to complete the upgrade? There are no clear instructions. I have 3.3 up and running, and prepared for my regular Tuesday nmight show; but will the 3.301 be ready for my Saturday show?
