update from wiki to wiki pro - install fails with a fatal error

I installed the trial version of Wiki Pro, and just now bought a membership and installed Wiki Pro. Or tried to. I got this error when I tried to activate:

Fatal error: Cannot redeclare class Wiki in /home1/saralaug/public_html/thegildedhour/wp-content/plugins/wiki/wiki.php on line 32

I would really like to get this sorted as soon as possible. Thank you for your help.

    Hello @Rosina Lippi Green

    Welcome to WPMU community!

    I hope you are well today and thanks for asking the question.

    You need to delete the free version first. If you access to admin, then from Plugins > Installed Plugins page, deactivate the free version and then activate the pro version.

    Otherwise, you have to go to /wp-content/plugins/ and delete wiki free plugin via ftp.

    Hope it helps :slight_smile: Please feel free to ask more question if you have any.
