A quick search and I simply must be overlooking the obvious. If memory serves, last year I purchased 2 DS licenses for a total of about \\\$400. At issue is yesterday, my desktop crashed and I lost the DS software I was using. Then, I got to thinking that the second license was most likely installed on a former employee's laptop.  

Plse forgive my ignorance of where and how to find my account info and what licenses (if any) I have. In addition, I may need to disable the license on my former employee's laptop. Thank you in advance, Kevin
