I am on my second year license. Can I purchase the remaining time to get a full license and the $80 upgrade to v 4 pro?

Helicon Focus v 4.0 quits when I try to process Sigma/Foveon X3f images. The thumbnails show but the program quits shortly after all images are loaded.
The same files work ok on v. 3.10.
thanks
