Hi, being new to this site and X Plane 11, I hope somebody can give me a steer. I recently purchased the LES SAAB 340a from X-Activation. However, when I try to activate the product throuh their installer App and add my email adress in the box as requested, I keep getting an error code that tells me to spesify a value. The box is clearly for my email adress. Has anybody come across this before? I have left two messages with X-Activation but have not heard back as yet.
