YouTube & Google are giving me a hard time! (For the first time)

Unlink my YouTube Account from a Google Account

This may be out of topic for branding, but has something to do with Social Media. Let me explain: To get into my YouTube account I log in with my Gmail account. What I found inconvenient and somehow annoying is that if I log into another YouTube account (from any of my clients or the one from work) I get logged off my Gmail account, being unable to use my eMail services. Sometimes I need to use both as the same time, but i can’t! I found this frustrating, and not practical.

I look up for a way to unlink the accounts, and found a way to do it on Google’s youtube support page. http://www.google.com/support/youtube/bin/answer.py?hl=en&answer=183819 the only problem is that once that the accounts are unliked, Youtube immediately asks you to link the account to an e-mail address. the following message appears. Please relink your YouTube Account to a new or existing Google Account. Well ….I just have ONE Google acount.

Please Google, I only have one Google account and want to keep it that way. I just want to log into my clients Youtube account or the company’s Youtube account without being logged off from my Gmail. Am i doing something wrong?
