The problem is, is that I have to reboot my machine after every attempt to clear out the wait symbol
No, you don't. You can simply kill the Couatl.exe in the Task Maanger after each try,
.we can see that it is couatl that is the problem,
No, it's not. You still don't understand what I've said: you haven't found Couatl is the problem, you have *disable* it, how it can possibly stop not being closed, if it hasn't even STARTED
I should try to un-install and re-install?
Just do what I said, go through EACH module in the DLL.XML and test one by one, until you find the conflicting one, and then do the same for the EXE.XML. DO NOT ever disable the Addon Manager or the Couatl program otherwise the whole test would lose any meaning.
You don't need to reboot Windows after each try, but do at least one reboot before starting. At every test, you can just terminate the Couatl.exe process with the Task Manager.
