solidworks mesh erorr

hello,

i recently re-installed my solidworks 2009 64-bit and since then i cant mesh a lot of objects.

the erorr that i get is somthing like: "surfece mash sucsesful, volume mash erorr, try redocing element size".

i get the error on large and small elements, i attach a part that i cant mesh.

what is wrong?

am i doing somthing wrong or is it softwere problme?

thanx a lot!!!
