Yeah, I guess so. Plus, they no longer do license-transfers so my serial is not valid for the English CS6 trial setup files I do have.
I figure I'll install the 30-trial of CS6 on a virtual machine and figure out which language-specific configuration files I need to copy into my German installation.
What a mess, they don't just provide the functionality to switch languages ... this is not quite the code quality I'm willing to subscribe to. Once I am comfortable with an alternative to Photoshop I'll be freed from Adobe.
