Version 1.4 is available for download.

I was able to find a workaround for the issue with uploads meant for an existing album going into a new album instead. Also, implemented an option for automatic checking for plug-in updates. The new option can be found in Lightroom Plug-in Manager in the Plug-in Info section.

Version 1.3 is available for download.

This update fixes issues with uploading photos cased by recent changes to the upload mechanism implemented by CVS Photo Lab. However, these changes are either incomplete or just buggy – you can’t upload to an existing album, even using their web interface – the upload is always directed to “Today’s Album”. Let’s see how soon they fix that. Until this is fixed, the plug-in is going to behave similar, unfortunately.
