relocate license

My draftsight has not been working well for couple months. Bought new computer hoping it is related to the age of my computer. Instructions ask that I deactivate my license on the original Draftsight (and older computer) but Draftsight will not open on the old computer - just keeps giving the message of Insufficient support of OpenGL outdated and wants driver updated...but drivers say they are up to date. so How do I transfer my license to the new computer if I can not deactivate from the old?
