Cannot access account nor access support

I have used my activation key-no success. I have tried to put a new password in it was accepted but when I tried to open the account an error message came up stated invalid information.
Also it requested the following in a box Users. what do I put in I only have the word User-Users name .I only have a numerical name for that. Password I put in the new one that I had requested.

When I tried to contact support-it request the Captcha- asking for the letters to be entered in-however there was no Catcha on that page.

Any help will be greatly appreciated
