Matrix Cube M4-B2

After selecting:
First console: Green
Second Console: Red
Third Console: Red

Right clicking on the Matrix Assembler, and choosing Yes. It tells me: "You do not have the right combination of Shards".

Any tips?

EDIT: I was able to make the level 15 Matrix Cube M2-W2 but not the level 32. Perhaps there are higher level matrix shards lying around..?

EDIT #2: It's not a matter of the level of matrix shards, but a question of how many shards you have. To make this Matrix Cube, you are required to have 1 Green Matrix Shard and 2 Red Matrix Shards (1 from Korriban another from Hoth) in your Mission Items inventory. I traveled to Tatooine where I purchased a Disassembler Cube (8k credits) from a vendor west of the Taxi in Mos Ila. Came back to Dromund Kaas, broke down the level 15 matrix cube, received my original shards, and then created my level 32 Matrix Cube with the combination provided above of GRR. The error message from the Matrix Assembler just happens to be lazy programming or miss-worded.

I hope this post helps.
