Keep your Communicator.msi handy
Well that was weird. I had a flaky SATA driver cause a blue screen of death on me a few minutes ago and after the restart Communicator wouldn’t launch. Instead, it was prompting me for the path to a Communicator.msi. Glad I had it on hand because apparently that crash damaged the app somehow. All was well after I pointed at the .msi and it repaired itself. Strange.
