Oh.. I just don't get it-
The downloaded dll worked for the localhost on both my local CS2 install (of my remote site), and the "stock" CS2 I tried earlier- both with/without "medium trust" in the web.config ... but still does not work for remote install.
I completely deleted the entire CuteSoft_Client folder.. and replaced with the local. Also replaced all the remote dlls from local, global asax, web.config.. still the same errors as originally noted.
I understand that my host (Crystaltech), as most, uses a "modified Medium Trust" which is Medium with a couple exceptions, which is, in fact, less strict than me adding the Medium Trust element to my local web.config... true? So I wouldn't think that were the problem.. but I don't know.
I am totally stumped. I can't figure anything else that could be different
