I thought that might be the direction we were headed.
I know I downloaded the files from the right place, but I'm in the habit of right clicking and choosing "save as..." or "save link as..." etc.
When I first downloaded the files, I clicked the links normally which took me to another page. I didn't see a download link there that I remember (and the structure has changed, so I can't confirm), so I went back up and right clicked the first link. Websites where this won't work usually show the file to download as "download.html" or something to that effect, but this showed the correct filename so I proceeded.
Obviously, that was my issue....
I checked this morning and found the "view raw" link on the second page and clicked that (again, I can't remember if I saw that before or not). I should have known something was wrong previously because the .zip wouldn't decompress regardless of what program I used (Stuffit, WinZip, etc.) so I was downloading the .bin files manually - or at least I thought I was. I even remember seeing a post about that, but couldn't find the "raw" download that was mentioned. Now, the .zip downloaded correctly and uncompressed with Stuffit.
I reloaded the two system files and the default image (v.0.2.3) and it booted up. I got different light patterns now (flashing magenta, then a fast flashing green, maybe a cyan and now the flashing blue) so I'm in better shape. Knowing that I've uploaded bad files, I'm guessing that everything will need to be sent again, but so I don't make things worse, what procedure should I follow to make sure it's all reloaded correctly? What pattern of lights should I see to confirm that everything is working correctly?
Thanks for all the help. I hate making stupid mistakes.
