Unable to install PSpice-fo-TI due to Access Key Usage

Hi, 

I downloaded the tool before and had been actively using it. However, due to my work nature that I need constantly switching PC/Laptop, I had installed the simulation software on > 3 PCs. This is the 4th time I am trying to install on my new lappie, but the below error pops up, complaining that I had exceeded the limit usage with the same access key. Can someone help me on this?
