Well maybe you aren't looking in the right place.
Using "softlock" (without the quotes) i got a link to this page:
http://www.kirchnersoft.com/ger/g-index.htm?/eng/news/e-SoftlockInfo.htm
which you identify as the maker of the LogiCad "platform" on which your target if running. This page, available in both German and English, has a potentially interesting title of:
Softlock Versus Hardlock
FAQ Special: Softlock License Service
which has some information on some aspects of the process of obtaining a license which should interest you.
You may be finding it difficult to find a home page for "Softlock" because the original company changed it name to Digital Goods around 2000 and then went out of business and sold off it intellectual property to pay off it's debts.
See: http://www.infotoday.com/it/jan01/news11.htm
There is a company at: http://www.newlife.co.za/softlock.aspx
selling something called "New Life Softlock.net" which could, and I only say could, have something to do with what you are dealing with. They have a free download you could look at to compare with your target's protection.
