Thank you very much, it helped a lot. Was quit easy now.
Now I have another problem.
I noticed I bought 1 license in 2013, but used the theme for 2 websites: anderhalfa4.nl and buropaasberg.nl
That’s not the way it should be, I realise now.

I used the update now again for both sites, but want to pay for this second license as well.
How can we do that ? Without trouble with the websites of course :-)

Hope to hear, kind regards, Marianne
