epson R2400 printing problems

Hi, new to forum hope somebody can help,
Using photoshop CS3 and Mac OS X Leopard 10.5, when printing on Epson R2400, selecting file-print-layout the following are all crossed through - print setting, colour management, print option extension setting and paper configuration. When I click on any of these I get a message which reads " the bundle could not be loaded because it does not contain a version for the current architecture, contact the bundles creator lsited here for the latest version. Have been trying to do this but have been getting absolutely not-where, does anyone have any suggestions. Have contacted Epson, they wasn't very helpful.

Just a very quick suggestion

Check you have all the updates for CS3 and for your Epson Drivers as they may be incompatible.

I know you said you contacted epson but just double check for updates on your printer drivers and for CS3.

Have checked all these still have problem, is it possible I may something ticked or not ticked in photoshop, as its just the advanced printing features I cannot use.
