Please make sure you update all the CuteSoft client files.

 

>>Do I need to do anything to my existing license file, or will the existing one for v4 work?

 

Your existing license file will work for the version 5.0.

>>Do any of the control settings need to be updated on my .aspx page for each instance of the Cute Editor, if so what should be changed/updated/removed?

You don't need to touche those aspx pages.

>>And (this seems like a popular one) what can we do to make our custom toolbar configuration files show up without all of the line breaks?  (The <g_end> tag seems to create a new line on the tool bar and any drop down lists seem to create some kink of unordered list tag which is showing up as a new line and a bullet.)

Please make sure you update all the CuteSoft client files. This problem should be resolved automatically.
