last year a collegeu of mine created a form on his IMac with the lightversion of webbuilder. Now we have to make some adjustments, but he is no longer working with us, and we don't use an IMac. So i've dowloaded the Windows version of webbuilder and i can open the old file . i can adjust everything.

But then, when i want tot save and publish the form i get into some trouble:

I must install a the, but the theme library is empty?
I must use an email template , but there isn't one.

what to do?

Customize the form to look the way you want.
Edit the email code to look the way you want.
