Hi, all. Just discovered a SIMPLE fix for all of this. Sick of "firewall not functioning properly"? Solution below↓ MaxNumFilters (DWORD) inside HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network and set it to a, NOT 8. Yes, just a letter a. After two frustrating days searching for solutions online, I became curious to see what the registry looks like in Windows 7 on my other PC. It showed "0x0000000a (10)". What? Just "a" but not "8" or any other numbers? Okay so I tried this on Windows 8.1. Saved and exit. BAM! Comodo now works great after reboot!
