haha, I tried to login as well, did not work:P
And now i tried with firefox, and it worked.
Something is not working 100% there, maybe try with another browser or rebooting until it is fixed :(
when i edit stuff in adminzone i get wrong pass sometimes, but the changes are done anyway... so perhaps it doesnt matter, i dont know. make sure you write the characters right, cause i believe this system is case sensitive and that could perhaps be the issue why IE wont let you through.
(For future references) I cannot reset pasword for you atm. However i can delete your entry making you able to upload the new version and set a new pass.
