Hi,
Thanks for the great photos of the problems you're experiencing.
Looking at your instructions, have you enabled the CodeCogs Equation Addin, by going to Tools->Addin ?
The other thing to be wary of, it that you should probably avoid using the Example sheet. This is another mistake we make with this earlier release, because the example sheet contains its only private copy of the equation rendering solutions, and this conflicts with the main one that you've correctly tried to install also.
We shouldn't have done this. Therefore assuming you have already enable the Addin; then again remove the toolbar (as discussed previously); The Enable the Addin (Tools->Addin). If it already Enables, then disable it, close excel, start excel, then enable the addin. If all goes well it should then create its copy of the toolbar which will correctly point to the appropriate underlying code.
Sorry you're having so many troubles - we're going to expedite our new version, I hope you can remain sane till then :)
Will
