Baby Lock Protege BL402 serger

I bought this same machine in l995 and have only used it a half dozen times.....because it is so difficult to thread. The only times I've used it were when the saleslady helped me get it threaded. If I had it to do over again I would never have bought it! When threaded correctly it works just fine but no sewing machine should be that difficult to thread!
