Hi! My name is Jean, and I just purchased a used Husqvarna mega quilter with Next Gen II frame. I'm so excited to get started with frame quilting and practiced a bit last nite. Tonight the thread broke and I needed to rethread the machine. For whatever reason, the automatic threader, which worked fine last night, didn't want to work tonight. I thought I needed to move the needle, so I touched the needle up/down button, and the threader mechanism fell off! I put it back on the post, but unfortunately, backwards! Now, I can't get the darn thing off, so I can't get it installed properly. Is there a trick to getting the threader off? I tried the up/down button a couple times, but now it doesn't knock the mechanism off (go figure!). Please, please help!!! I'm an absolute newby at this so will appreciate any advise you can give. Thanks!!
