Can't connect devices

I had posted a problem not top long ago where a bunch of my files were deleted after connecting two folders. In an effort to fix this i uninstalled the program on both machines. Upon reinstalling, i no longer can connect the two devices. Both are stuck at “disconnected”. i have tried uninstalling with Revo and restarting both devices and reconnecting and anything else i can think of. i just have no idea what else to try. i got them to connect the very first time i installed/ran the program…

i would post config and log, but none have been created on either machine…

Are they on the same network? Is there a firewall?

They are on the same network and i have adjusted the firewall.

i just started up the second device, a laptop, in linux and installed/ran Syncthing and that connected fine. SO my PC and my laptop (liniux) are connecting, but not my PC and laptop (windows 8.1)…
