Hello,
at the first time, thinks for this great tool and this new version.
I've noticed that it "is a bug when I want to upload my CharacterProfiler.lua to update my guild stat and nothin change, just my personal roster update...
My pass is stored in my browser with *** and so it is bad save and the roster work as if it's no password...
It was great to see an error message for the pass, isn't it ?

Uhm....what?

The password is required if you want to update the guild list
No password is required to update just your characters

No error is given because...well...because it isn't

I think that it was great to see an error, when it's a BAD PASSWORD, no ?

If your password is stored in your browser and shown as **** and you think its bad/wrong then clear your browsers cache, close it, open up a new browser window and try again.

Make sure you've got the latest versions of the guild and character profiler addons, start wow, log in to your character and do the usual thing for saving all your stuff, including opening the guild window to save your guild list. (I'm not sure if you have to show offline members to save them too, just do it to make sure)
Exit wow, then try the uploading in your new browser window.

Its debatable wheter to show an 'incorrect password' message or not on wrong password entry. It may eleviate some user confusion but also make it easier to guess the right password which can be dangerous. (Most ppl dont remember 50 passwords for all their stuff so they use at most 3 or 4 for everything together)
