Did you know Squad 44 actually generates log files whenever something unexpected happens? You can actually use them to troubleshoot why something bad is happening (or send them to someone else who can)
The default save location for Post Scriptum log files is %LOCALAPPDATA%\PostScriptum\Saved\Logs
You can paste that directly into your start menu or windows explorer and hit enter to open the folder.
Inside this folder you will see .log files (these can be opened with any text editor like notepad or wordpad) the one named "PostScriptum.log" will always be the newest, when a new log file is created the previous one is renamed to whatever the date / time is.
Attach this log file, or the entire folder to a Support Ticket to help us troubleshoot your issue.
