I'm trying to use the Beta Tester plugin to help beta test WP 2.9. Give back to the community a little and all that. I'd prefer to use this plugin as its so much easier than the manual upgrade. However, I get this error every time I click the upgrade button:
"Downloading update from http://wordpress.org/nightly-builds/wordpress-2.8.4-latest.zip.
"Download failed.: Not Found
I'm not sure what's wrong. Any ideas? It struck me that perhaps "2.8.4" is incorrect in the zip file's name, as it should be 2.9 or something. 2.8.4 is what I have installed currently and is not a beta version. But if so, I'm unsure of how to change it. Any help would be appreciated.
