Issue:
Some Windows 10 users have experienced problems with RSS Authority Sniper not being able to successfully search for feeds or crashing during feed search.
Solutions:
1. Go to 'Windows Compatibility mode' for the application and change to Windows XP with Service Pack 3. (See this tutorial on setting compatibility mode in Windows 10 for a step by step on how to do that.)
2. Check your anti-virus/firewall software and make sure that there is an exception or whitelist entered for RSS Authority Sniper to make sure it is trusted to access the internet.
