I hate computers!

I've been working all day trying to download a new set of maps for our Garmin. In fact, I started this process last night! It's taken about 7 hours to get the new maps to the computer - NOW I have to get them from the computer to the device...aargh! Nothing seems to be working right...I don't know why I can't just blink and it be done! Oh, now I'm getting "an unrecoverable error occurred - exit and start over." I have a feeling I'll be on the phone to Garmin tomorrow again!
