I have arden software impact with dongle which i purchase 10 years ago from (marbac) germany and i have a german laser with me ! Now the thing is i am planing to buy a new laser (slab laser 1500w) for that purpus they are asking me to buy a new software which is very expensive ! The name of the sofware is (diemaker lite) by arden itself ! Does any one have any idea what the software is all about !!
