I have a copy of Fluid Mask 3 and I used this software for a while. I have to remove it constantly because I have a small hard drive and I need to make room for other software. After utilizing the new program and removing it, I reinstalled correctly the Fluid Mask 3 for two times, but after that I it keeps asking me if I'm using it on another computer. The answer is no. I have only one computer and the reason why I remove the software is to make room on my hard drive. Can you help?
