To access your old save game files from previous versions you must do this:
Before running this new version open the folder "C:\Users\\AppData\Roaming"
rename folder named "Urban Voyeur - Standard Version 0.1.2" to "Urban Voyeur - Standard Version" (*)
run this new version, your old save game files should appear now.
(*) if you already have a folder named "Urban Voyeur - Standard Version", delete it first, and then rename "Urban Voyeur - Standard Version 0.1.2" to "Urban Voyeur - Standard Version"

For Mac, the save game files are located at /Users//Library/Application Support

For Linux, the save game files are located at /home//.config/


I did this and all my old save games worked just fine with this new version.
