Hi everyone, I bought a Pro's Pro Challenger II machine this week and I tried to string my frist racquet today. It's very hard to do for me haha, but something went completely wrong I guess. This is how it went: I put the first mains in it and secured it in the quick release, after that I pulled down the weight but the string didn't get any tension. So now my question is: Am I doing something wrong? Any advice is appreciated!
