System - SIMGallery plugin prevents JomSocial registration .... please help!

Mike, I have an issue with SIMGallery, when I enable the System - SIMGallery plugin, it prevents the JomSocial registration from working. The JomSocial registration doesn't advance past the first screen unless I disable it, but then if I do JomSocial photos and videos no longer default to SIMGallery. Can you please look at this asap? Thank you!
