The more you tell us, the faster we can help. A quick "it doesn't work" takes a lot of back-and-forth before anyone can dig in — but a message with your version, the exact error, and the log file attached often gets sorted on the first reply. That's true for our in-app assistant too, and you can ask it for a human anytime.
First, please update to the latest version — your issue might already be fixed. Click the o/PARASHOOT icon in the menu bar, open More, and choose Check for updates. If it turns out you were already up to date, great — now you've ruled that out.
Also open Settings (menu bar icon → More → Settings) and check the Full Disk Access row shows Granted — a missing permission causes many detection, erase, and restore problems.
What to include
Your o/PARASHOOT version and your macOS or Windows version
The card type and the card reader model
The exact text of any message or error the app showed — a screenshot of it is ideal
A short screen recording if the problem is something happening, or not happening, in the app
Your log file — see below
How to get your log file
macOS
Click the o/PARASHOOT icon in the menu bar, open More, and choose Show log file. The log opens in Console. Click the Reveal in Finder button to show parashoot.log in Finder, then drag that file straight into the chat to attach it.
Windows
Click the o/PARASHOOT icon, open More, and choose Show log file to open the built-in log viewer. Click Open Folder to locate the log file, then drag it into the chat to attach it. For a quick issue you can also use Copy All and paste the contents into your message instead.
Screenshots and screen recordings
A few seconds of recording showing what actually happens is often worth more than a long description.
Screenshot (macOS): press ⌘⇧4 and drag over the area you want.
Screen recording (macOS): press ⌘⇧5, choose to record, and capture the moment the problem happens — for example, clicking erase and what the app does next.
