Yes, there is a big note in the website telling that it doesn't work in CC14. 

Please see the website FAQ.

Paul,

The project is delayed, sorry.
There is going to be an update, but I can't say a date.

Abode is dropping Flash planels from CC 2014, that means I have to rewrite all the plugin. It will requires some time. Probably later in September I will have some version.

Is it happening in all cases, in different computers?
If you send me some examples files with the problem I can take a look.

Cut&Slice me only works on Photoshop CS6 or higher

Please use the version 1.1.2 then:

I will take a look to this error. Sorry.

Have you tried to install it in the Photoshop CC 32?

in version 1.1.3 XXHDPI is added and LDPI is dropped.

This is weird. The plugin doesn't export HTML. From where are you trying to export? :P
