just tried to install your plugin and got the following error.
I think that you need to make some clean-ups in source code. I suggest you to delete unused ACE files. For example, ACE don't uses folders like demo or kitchen sink and many others.
There is a screenshot with only one required folder in wpide\ace-0.2.0. And other folders (not highlighted on screenshot) have a size 22.6 Mb. This is a giant size for wp-plugin.
Also, the current version of ACE is 1.1.01.
Thank you for attention and for the great open-source project.
