Can't Connect - "new client is unresponsive"

[Google Code Exporter]

What steps will reproduce the problem?
1. I run synergy on my PC
2. I configure the server and set up a new device named "iPad"
3. I run iSynergyClient 0.8 on my iPad and enter the server address and "iPad" 
under client name
4. I tap the switch for "Mouse" under "Activation" in iSynergyClient 0.8

What is the expected output? What do you see instead?
I expect the two devices to connect, but this is the dialog that pops up in the 
Synergy desktop log:
INFO: watchdog status: ok
NOTE: accepted client connection
INFO: crypto mode: cfb
NOTE: new client is unresponsive

What version of the product are you using? On what operating system?
I'm using the 64-bit Synergy app on Windows 8.1 and iSynergyClient 0.8 from 
BigBoss on my iPad 3.

Please provide any additional information below.
Full log from Synergy:
NOTE: connecting to service...
NOTE: connection established

WARNING: detected application not running, pid=6304

I also tried leaving the client name blank and entering the other device name 
in iSynergyClient, but had the same results.

i fixed the device unresponsive by disabling encryption in the server. its like 
the server is waiting for the password input but the client isn't popping up 
asking for it.

But I too am getting the crash to safe mode when trying to move the mouse into 
the screen. ive installed BTC mouse and keyboard but that doesn't seemed to 
have helped.

Anyone having issues when hitting the home button and it turning off?

Noticed the same issue.  My server is 32-bit Ubuntu and client is Windows 7.  
Noticed that the USE SSL ENCRYPTION setting is grayed out (not selectable) on 
the server settings.  The client defaulted to USE SSL ENCRYPTION selected.  Had 
to DESELECT that option on the client and it worked.  Wonder now if SSL 
functionality is not available on UBUNTU 32-bit.
