i have a viking designer one, last winter, 2 weeks before christmas my machine did the same thing...got stuck in reverse...no amount of 'fiddling' worked for me...i called the dealer, they made it sound like a HORRIBLE, EXPENSIVE problem...so i waited till January, found a place a little closer than the dealer and sent it in to them to check it out...they cleaned it (there was alot of lint built up, even though i am pretty diligent about cleaning it between bobbins) as soon as he had it cleaned it started working fine again...not an expensive fix but a wake up call...
