For some stupid reason, I downloaded and installed 2.65A and now, my EPSON Perfection 1650 Photo scanner does not work - the buttons, opening the scanner app directly, or from inside Photoshop.

On top of this, there does not seem to be an older version (2.34a) anywhere for the web, and going to their FTP site is of no help as they name all their files something totally incomprehensible (epson10952.sea.hqx).
