thank you all for the help so far. i don't want to give them any information.but not knowing how to deal with this properly i am just checking my options. i really don't want to say anything i shouldn't.but i do want to give a minimal legal reply,i'm just not sure what that should consist of.

i feel i have to reply somehow but am unsure how to, i no longer have the router as i have changed ISP since then. i also know nothing about how it got downloaded so can not provide those details either? all i do know is that i didn't do it.and have never even heard of the band,or the site that it came from.

i have replied to the first 2 letters with thanks to this site.but now i have letter 3 and am starting to think this is never going to go away. the first part is saying how the processes and methods employed by there IT experts produced enough evidence for the high court of justice to have my information released by my ISP.and therefore remain that there has been no mistake and that my internet connection was used. then whilst your computer may or may not have been used to commit the infringment act this is not the basis of our claim.similary,we do not claim that you downloaded our clients work although we do not exclude the possibility of this. then they ask me to provide 1) the manufacturer and model number of the router. 2) date month and year router was provided. where you are surgesting a third party may have used your connection,provide. 1)clarify if they were autherised 2)step taken to determine if your internet connection was used 3)identify the person with name and address. with 14 days to reply then 3 pages of explanatory notes on wireless security HELP PLEASE is it time i went to a solicitor?? they asked for no money this time? just those details.

i have received a letter from ACS:law saying that an ip address has been identified as me(by court order to my isp) has downloaded a (work) scooter, jump all over the world( whom i have never heard of?) and i now have to pay them £500.00 in 21 days or be taken to court? they are working on behalf of digiprotect gesellschaft zum schutze digitaler medien mbH. please help! what do i do?
