So I recently decided to upgrade the operating system on one of my pc's to windows 8. I know my pc's specs are fine for the upgrade via microsofts site. I bought a digital copy off microsofts website and I get get past the first stage to get the installation files. At first it gave me an error say "Download did not complete. The per-block retry limit was exceeded. File is corrupt." which I was surprised since the set up file was from microsofts own site. Got that error a few times and now it just says "unspecified error". I am really upset especially since this copy was a gift. Has anyone gone through this because the microsoft support team seems useless when I try to get there help.
