cannot connect to remote computer as i Team viewer decided its for business use

I have been connecting to a remote Laptop in Manila Phillppines for past 6 years to help a dear friend who is Computer Illeterate senior citizen for teaching her about computers and helping her maintain her laptop.  Recently she moved in with her sister for health reasons.  The sister uses her business account i believe to provide internet for all family members in the house.  Otherwise I believe I should not have a problem. But when I tried to connect I was not able to connect.  The purpose is personal use only never business use.  How can I connect to her without Teamviewer saying its business use?  Is there a work around.?  Many thanks in advance.
