Update - received email in letter format, un-registered post. So nothing was signed for. Awaiting next stages, whatever those may be to see if I need to respond.

New to the forum and this thread is why I've registered to add to the list.

1. Received an email from Solicitors stating they represent DSSW - infringement of copyright without license
   
2. Identified, correctly, MAC Address - used 20 times between 20xx - 20xx
   
3. States 'company is not licensed to use software
   
4. No mention of IP address
   
5. Mention of 'damages of at least....(value of software)' and sale price of software. Listed example cases of awarded damages, apparently
   
6. Contact must be made within a few weeks to contact the writer. Detailed resolution to include 3x elements
   
7. Mentioned any attempt to delete software.....well it's a bad thing and can be detected
   

Posting to add to the 'targeted' initial email list. So expecting something in writing end of the month or so.

Certainly gets one thinking. I've read through this thread several times now and still uneasy.

Cheers for the posts thus far,
