[xwiki-users] After installation, Admin cannot log in

Hello, I've installed xwiki from the standalone installation and have chosen to use mysql instead of hsqldb. I run the server and everything looks great. I can get into mysql and see that the tables are populated, and I see the web pages in firefox. But, when I then try to log in using Admin/admin, I receive a "wrong user name" response that prevents me from going any further. I've tried variations on the log in (caps, no caps, etc.) but nothing seems to work. If I attempt to add a user (not logged in), there are no errors but upon pressing save, the user list does not update for the new user. In addition, I looked at the database table xwikipreferences (I assume this is where the user names and passwords are stored) and the username is not there. Here are my specs: xwiki 1.3 windows vista mysql 5.0.14 JDK 1.5.0 I've searched through Nabble, xwiki.org, and google but haven't found anything that has helped. I'm emailing the list to see if anyone knows anything about this or whether this may be a compatibility issue. I've also tried this with the graphical windows native installer and encounter the same issue. As a side note, with the graphical windows native installer, I notice that the css and js files do not load but images and text do. Any help would be very appreciated, Greg
