Cannot add several apps

Cannot add several apps

I previously tested a few zoho apps and recently made the decision to go with zoho one for my small business.

I can add most apps, except the ones I tested.  I get the choice to create a new account, or choose an existing account.

My preference is to create a new account but when I do I get "an error has occured"

Im unable to choose the existing account either because the radio button is disabled.
