The July 24th version is at the web address provided by the error message. Perhaps you have more than one installation of EverQuest 2 on your computer and you're replacing the wrong one?
Make sure that the one you're replacing is the one that that innerspace is trying to launch.
The only other thing I know to tell you is to install Teamviewer (you can google for it) and then email me the information to look at it myself at
amadeusmq@yahoo.com. I can look at your computer and probably see very quickly what the issue would be.
