Yes jessman, it appears the problem is with those missing templates. Without them it doesn't write the HTML for display, thus you get blank screens. I have made a zip file available to download containing the complete file structure including the missing html from the SVN. This is not the latest version in development but it is the version in the SVN (current version is only viewable at myroster.dontexist.net). Most new changes are small bug fixes and updating the admin section with some user admin changes. You can obtain the zip file at this link: http://dev.pkcomp.net/uploads/accounts_199941_444.zip
Just un-zip the files into your addons directory and try Accounts again. Don't forget to change the roster auth setting to Accounts, otherwise you will not be able to use many features.
