Pin planner SSRAM

Hi!

I'm currently using the Cyclone 3 development kit, and I'm trying to use the board feature SSRAM. However, I'm not sure I've got my pins configured correctly. During compilation with Quartus II v8.1, the Analysis & Synthesis returns no critical errors, but the Fitter returns the following and the compilation fails:

Error: Can't reserve pin "address_to_the_ssram" because its name already exists with a different direction

Is there a solution to this problem which I do not see?

I've attached a .zip-file which includes a excel-sheet with the pins and locations I've used.
