Hi there! I understand you're having issues logging into Purrrr after reinstalling the app. Let’s see if we can get that sorted out together.

First, can you let me know if you're receiving any error messages when you try to log in? Also, did you try resetting your password just in case?

In the meantime, here are a few steps we can try:

1. Check your Internet Connection: Make sure that your connection is stable. If you're using Wi-Fi, try switching to mobile data, or vice versa.

2. Clear Cache: If you're still unable to log in, it might help to clear the app's cache. Here’s how to do that:
- Go to your device's Settings.
- Tap on Apps or Application Manager.
- Find and select Purrrr.
- Tap on Storage and then select Clear Cache.

3. Reboot the Device: Restarting your device can resolve many connectivity issues.

4. Update the App: Make sure that you’ve got the latest version of the app. Sometimes, an outdated app can cause issues.

5. Check for System Updates: Ensure your Windows 10 is fully updated as well.

If you're still having trouble after trying these steps, we may need to check if there are any known issues or outages related to the app. Let me know how it goes!
