When Personal and Work id's are the same cannot log in to app.powerbi.com

I have hit a small snag.

I have a Microsoft “Work” account like me@company (through GoDaddy.)  This is a Premium account and includes my email account, and my PowerBI account.

For BizSpark I have a “Personal”  account, also me@company.  (I fear using the same email ID in both cases may have had unintended consequences.)

When I go to app.powerbi.com, I am asked to log on with me@company, and it takes me to the GoDaddy sign-in and I log on successfully.  However I then get this:

Link to Error Page 1

Selecting Sign In above gets me this:

Link to Error Page 2

It would appear it is picking up my “Personal” BizSpark account and disallowing access. 

How can I fix this problem?
