Hi,
I have had the same problem and have been searching for a solution for several weeks with the help of the people working at our CoffeeCup.
I think the final result is that what is quoted below.
"Hello Henny,
The problem is not only that the images are on both computers, but that you are moving the project from one computer to another. You will need to keep the project on one computer, or you will receive that error. This is because the images have different file path locations on either computer. If you want to switch the same project from one computer to the other there is only solution that we have found that works so far. That would be to have an external hard drive, or usb drive with enough space to handle the amount of images/files for your website, rename the drive to an unordinary name such as drive R:, then place all of your files in a folder on that drive. This is so that it will not be able to change the file path when you move from one system to another.
Thank you,
