How can I export a 2d mesh from ICEM to Fluent?

I created a simple rectangle(1*1) from nodes and lines then made a surface of it. I created a part for each edge. then made a blocking and defined the nodes on the blocking edge. gone to pre-mesh and then file->mesh->load mesh from blocking.
then saved the goemetry, blocking and mesh.
went to output tab selected fluent and then created a B.C for each edge.
Then I clicked on write input. opened the mesh file and saved the file.
In fluent when i try to open it gives an error "file has wrong dimension"

Am I doing something wrong?

thanks for your help
