Hi! I have had my machine for about 2 years now. I took my blade out to clean it and when I went to replace it, it was no longer cutting... as if the blade wasn't going all teh way down even though I inserted it correctly. I thought maybe it was just time to replace the blade so I put in a new one but it's still having the same issue. I'm not quite sure what to do. It'll go through the motions as if it's cutting and some pieces seem to maybe cut a bit, but other just seem like the vinyl is untouched or was just skimmed. The blade has been put back correctly though, I'm not sure what's going on. Any suggestions on what to do or what to change?!
