Wild West Domains are your Registrar on record, and they are capable of providing help (even if you went through a reseller). I have no idea if they will. http://wildwestdomains.com/support.aspx
Using the whois on GoDaddy.com I see that you registered it using http://fxdomains.com/
. If you enter an incorrect username and password on that page, it takes you to a site where you can retrieve your password. I assume this is the email address which does not work properly (tmachine or something?). They have a PDF form which you can fax to them to change your email address, this might be your best option.
Do you control firstname.lastname@example.org
? If so, after 60 days you will be able to move your domain to another registrar anyway.
Incidently, I am a TUCOWS reseller myself and currently manage (and sponsor) several community domain names (xith/xith3d, odejava, odeed). For community sites, I'm happy to provide domains at either cost price or free depending on the site.
