I have a Google account for ages and I used it for Adwords. But Now I have to logout and log back in with a different account for another Adwords campaign groupso my personal account has a canceled Adwords account. I tried to link my personal Google account to the active Adwords account, but that is not allowed because my personal account is still linked to an (inactive) Adwords account.Now I have searched the newsgroups from Google for this and found a solution. Go to Google account settings, products and hit 'edit' but there is no option to permanently delete the inactive Adwords account.All other solutions include a new Google account, but I use the Google account for to much to give up.please forgive me if this is not the correct SE website to ask.
Google Adwords and MCC account issue

I'm pretty sure in AdWords you can have multiple emails associated with one account (so two people can work on the same AdWords account each using their own Google Account). Have you tried creating a dummy Google Account associating that with your inactive AdWords account, make it the primary account holder and delete the other - essentially your not unlinking the account but instead transferring it.
