That is absolutely crazy. Is there a Euro version of Amazon.com you could look into?
Even if you did get a US (english) version would it be compatible with your Euro version of your operating system?
This might be a possible work around. Go to Wacom.com
They are the makers of Wacom tablets. IF you buy one of their tablets they provide an offer to get Photoshop for 50% off.
So, if you buy a 229.00 Wacom tablet, you can get Photoshop for 350.00. So a new Wacom tablet and Photoshop will only run you 579.00. You get both and still pay less than a single copy of PS
It only applies to the Intuos and higher, but either way, you get two for the price of one.
