UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Help! CAPTCHA Not working on new server

Ok, on my old server I was using ImageMagik for the CAPTCHA in the registration and it worked great. On my new server it isi not working. I do have IM installed and I've checked that the paths to convert and mogrify are correct. Yet, the CAPTCHA images are not showing when using IM (but they do work with GD). I need to get this fixed becuase my forum is not the only thing that is using IM. Any isdeas why IM would not be working for CAPTCHA given that the paths are correct?
