You have registered the counter under the neopets name, mamksonv1n. You are trying to access the counter via the neopets username v1ncenzo. It's a security measure designed to prevent hits stealing.

[quote]Note: If you don't intend on using this service, please do not create a counter as it only clogs up the database - thank you. Please type in your NEOPETS username as EXACTLY as it appears on your userlookup. This means, no capitals, etc. Update: I updated the script so if you didn't bother reading the above RED text, it'll automatically convert everything to lower case anyways. *shifty eyes*[/quote] It says username though =/ Anyways, I'm in the middle of moving everything over so within an hour or two, you should be able to create one again.
