I recently dug up an old Square-1 from about three years ago that I got from Thinkgeek.com (although its called the irregular IQ cube on their website). The stickers are falling off, it is really dirty and stiff, etc. So, I decided to get some new stickers from Cubesmith and clean all the pieces. After I took apart and cleaned it, I looked up a tutorial on how to put it back together and it said I had to to screw in a screw on the center cap once the two halves have the pieces on it. Well, when I go to screw it in, the screw is flat so I can't put a screwdriver into it and I can't screw it back in. Does anyone have experience with this cube and know what to do?
