How do I link my account with another SWID?

Can you please assist me in linking my SolarWinds account with another SWID that I will be managing?

I have tried to do this under the customerportal using the "LINK PROFILE TO ANOTHER SOLARWINDS ID" but I am getting the following message:

ERROR:The combination of Email: xxxx and SWID: xxxx  is already used for other registration.
