The site loads and tells me that the session is over. Can you post the model of your Toshiba laptop?
As for installing RAM on a laptop usually you can install it via a compartment on the bottom (usually square-ish). You unscrew the top of the compartment and you should see one or two memory slots. You insert the sticks at an angle (around 45 degrees) into the slot and then push it down until it clicks into the handles.
Now if you only see one memory slot there but your model has two then the other memory slot is usually under the keyboard so you will need to remove the hinge cover (if neccessary) and the keyboard to access that slot. Or the memory slot can be on the motherboard so you will need to remove the palm rest to gain access to it. There should be a manual of your model on Toshiba's website that details where the memory slots are.
