Unable to Login to Acrobatusers.com

I bought a license of acrobat pro extended.

I have been trying to gain access to these forums for 3 weeks now. I have tried setting up accounts for my work email, and my 2 personal email accounts. Finally one of the techs at Adobe have managed to get me access through one of my personal email accounts. I would like access through my work email, as to not flood my personal email account whichg I cannot access easily from work.

The problem is as follows:
1. Created a 'free account' from the acrobatusers.com home page.
2. Entered login details.
3. Received a "invalid username or password" error message.

Attempted troubleshooting:
1. Clicked 'forgot your password' link
2. Waited 1 day for email to be sent. (This did not arrive)
3. Clicked 'forgot your password' link.
4. Email arrived immediately with a link to reseting my password.
5. Clicking the link brought me to a page stating "You have already used this one-time login link. It is not necessary to use this link to login anymore. You are already logged in"
6. Every subsequent attempt to reset my password returns the same error.

I have tried sending an email to web_master [at] acrobatusers [dot] com and tried to send emails through 'contact us' and my messages were ignored.

Can someone please help me find a way to resolve this issue.

Thanks for your time.
