Problem with the upload script ?

Hello, I didn't manage to upload the new release of Cache_Lite (1.1). The package.xml seems ok (pear pv => ok), (pear package => ok). When I upload the file (Cache_Lite-1.1.tgz), it seems to be ok (Please verify that the following release information is correct... => it's ok). But when I click on "Verify Release", I'm blocked by the following message "Package not registered. Please register it first with "New Package"". Yet, it's certainly not the first release of Cache_Lite. Any idea ? Thanks :) Fab
