Do you have an extraction program? WinRar? WinZip? 7Zip?
This.Because I have Win 8, and had no problems with it. o.o
If you played EPW on your old pc and still have all the files on there, network epw across from old pc to new laptop.
Yeah i was thinking of doing that would be a lot faster and easier, however i will have to go borrow a USB.
You can link your PC's directly with a network cable/ethernet cable.Would probably give you a faster transfer speed too than doing it by USB.
If you're downloading a 7gb file in less than 5 seconds, there is something corrupting your download. Try disabling your antivirus while you're downloading. Or you can transfer from your old PC to your new one and hope the files don't get corrupted. I have Windows 8 as well and had no problems downloading, extracting, updating, etc.
You would have to walk me threw the steps to active that im not a super computer wizzy but i do know the basics.
