My number of activations for my copy of 2.5 has run out, and Lockheed’s support has been unresponsive over the past week. I am wondering if is worth it to upgrade to v3.x from 2.5. I have several FSX planes that I enjoy that won’t work in v4.0. A2A P-40, and the Classic Hanger FW-190s. Will they work in 3.x, or should I just buy another lisence for 2.5?
