I have been using Acad 13 for 10 years or more - when it first came out. Now my computer crashed and I have the CD but have long lost the start up disk, s/n etc... whatever is needed to install it. I checked on ebay and they are selling version 13 for .50, etc. So I'm hoping some kind hearted soul will email me a working ID. Will be glad to send you a few blank CD-R's or a few dollars something in return. The email below is good - just delete REMOVE. Thanks, pals.

(If anyone doubts it, just tell me how to hold the CD and I'll take another photo and post to prove I really do have the CD.
