Followed the guide and completely uninstalled the previous version before downloading the new one.
Two problems in the last five minutes:
1) Access violation
2) Wine Gecko Installer - Wine could not find a Gecko package.
The second issue occurred when I opened an individual's details and then clicked on Media Album. Now the system is non-responsive (I mean the buttons depress on screen but nothing happens) and the only way out is 'Force Quit'.
