1) Delete ALL MyExpatNet.app files from the Applications and Downloads folders
2) Delete the MyExpatNet folder from Macintosh HD/Library/Application Support
3) Delete the MyExpatNet folder from Macintosh HD/Users/username/Library/Application Support
Last one is a hidden Library folder so you access it by being in the Finder (basically just click on the desktop), clicking on Go in the top menu and then holding down the Option key on the keyboard to make Library appear in the drop down menu. Select Library and then go to Application Support and delete the MyExpatNet folder
Once those are deleted, empty the bin, do a restart and you can install new version.
