Alright.... I will explain again.
I downloaded the NEW wzrhpg300nh-pro-v24sp2-14998 last night from my desktop, tried to upgrade and it was then that it said "Invalid file".
So, I re-downloaded the file again this afternoon about 3:30pm, tried to upgrade from my laptop (wireless), looked like it was going to work, then it gave me a different error. This time is said "upgrade failed".
I will clear everything again and try again.
Thanks for the help everyone.
