Installing WOW on my Computer, an epic journey...

After getting a trial DVD to install WOW, I got a bit frustrated because i had to download 3.3 GB of updates and even worse, once the download was complete, it started downloading additional patches, the whole thing took about 2 days to finish, last night at about 10pm it finally ended, but sadly an error was found while trying to overwrite a file, I must admit I was a bit angry by then, so I just went to sleep hoping that I'll be able to finally start playing the game today.

It's good to mention that i think the installation process should be improved in any way, it's not nice to wait that long in order to get the game up and running, something similar happened to me when I was trying to install Star Craft II, took me about 3 days and when it finished downloading the necessary stuff, my trial period was over, so I couldn't play the game =( .
