Sticking so badly you cannot edit HD files on Magx15. Is there a patch for this. I have a high spec computer with lots of memory, even half or quarter resolution does not help. I downloaded a big update only for the installation to tell me Magx 15 edir pro was not installed on my system!, although it is of course installed and registered.
You may have to reinstall and re-register MEP15+. Then install the update... This is what I just had to do, and it works, finally!
Also, make sure you're getting the right update for your MEP version. There are different updates for the E-Version (download) and the boxed DVD version. They install into different folders on the computer and thusly the update won't find it if it's looking for the wrong one. To be sure, you might use the HELP->Online Update function from the program's menu.
