I'm in the same boat as this guy. I'm having the same issue. I have been through the steps mentioned in all of the prior information in this thread to no avail...

Ideas?

Mine is in a development server - I'm trying to learn zencart and integrate it with my site before going live on a legit host...

Its a brand new install, its on a local IIS box, I've been through zcinstall twice, so i kno3 my username and login, but it never continues past the login page...I've tried multiple browsers, multiple computers, clearing out the cookies, etc...no luck...
