Answer 1

I closed my virtual devices, opened windows task manager, and killed all adb.exe tasks -- there was one constant one and another that would appear then disappear. Aftwerwards, i started my virtual device and everything worked again.

Answer 2

Make sure that no other program is trying to take control of the ADB. You can check this by opening task manager, right clicking on any of the adb.exe, and opening the file location. Turns out that my HTC sync manager had it's own ADB and wanted to run it all the time. I uninstalled the program and haven't had issues since.
