Serial numbers are provided to protect copyright holders and rightful licensees. Providing them for others to use with pirated software contributes to copyright infringement and the circumvention of technical measures, and is illegal.
Most software publishers have provisions for replacing media.
Contact them to resolve your problems. Software is so expensive, and I've wasted a lot of money just to find out that an expensive program does not meet my needs. If it's any good, then I'll reward the authors. Unless the software publisher allows, you cannot copy software and pay for it only if you want to at some later date. Your dealer should be able to provide demonstrations of various software products before you buy.
