Hi isabel
I have a powerful DLL that return HDD serial number ( Manufacturer serial ),HDD name ( Maxtore , Wester Digital,...) and a computer ID and some other info.
I think Time lock is not powerful because users can change their computer time.
But when you check record number of database ( RECCOUNT() ) they can not do anything.
I can send to you this dll if you want. i make a powerful lock for my programs and for 3 year anyone can not copy it to any system.
