Synergy 2.0 worked for me for about 10 minutes after I initially installed it (I joined the party at Beta 4). Ever since then I have been getting a message saying "There was a problem connecting to the background service. Retry". Retry of course does nothing. I have tried every beta and RC up to current (RC2) thinking that at some point this issue must be fixed. It hasn't. I have tried the troubleshooting steps and I am fully removing the software before installing the new versions.
