I purchased a license for Seismaster in 2010 (PRO 7.0.2_0). What would be involved with getting an updated software release?
The developers are out of business, which means the software is discontinued. I have located the official website and accessed it, but a domain error is displayed instead. Their website and their hosting have been discontinued.
You can try another application from the same field of work called OpendTect. It has a website where it can be downloaded as well.
