latex use is broken with textext 1.3.0 and miktex

[PinkMushroom]

After a considerable amount of effort making sure textext was working correctly, I still get an indecipherable error when latex is enabled. The good news is that circuitsymbols works if i disable latex.
I would not be surprised if this is the result of yet another missing package in the latex installation (that was the problem i encountered with textext).

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

and there it is at the very end, i just wasn't patient enough to read through all the messages.
You also need the following packages

and then success! Thanks for your help.
The latex output really does look good of course, but it's a bit of work to get there...
p.s. this is a very cool package.
