Cannot update the Titanium IDE in Ubuntu 13.10

Greetings, I have just installed Titanium Studio for Ubuntu 13.10 x64-bit. I made sure to install all the dependencies. The problem I have is when I start the program a pop-up window appears giving me a list of Titanium Updates. I select install, input my password and nothing happens. When I looked in the log I found this:

!ENTRY com.appcelerator.titanium.update.core 4 2 2014-01-01 20:26:23.750
