Fluid Mask - 3.0.9 For Mac

This is my first commentary on this site, although I do use this site frequently. I've owned Fluid Mask for 2 months. I watched all the video tutorials on their site, which are quite informative. As a photographer, I had some difficulties masking people with dark hair who were in front of a dark background (low contrast). The same was true for lighter skinned blonde people in front of a light background. I contacted, via phone, their technical support department who referred me to their technical support technician, Mike. I tried to contact Mike multiple times over 5 weeks. I also sent emails to him with the pictures I was referencing, in order to get some specific work around. After attempting to call (long distant) 8 or more time, with multiple repeated emails, I still have not received an email or a call back. I actually called yesterday, leaving a message that I was going to leave a comment on this site about the lack of technical support, and they still did not contact me back. The site tutorials are a good learning tool, but please be aware that the contrast between the background and foreground, which is where the masks occur, is very strong. Most pictures to not have such a contrasty background. I use Photoshop extensively, but could not come up with a way to utilize Fluid Mask appropriately using adjustment layers or filters. I was disappointed with Vertus' lack of professionalism in never getting back to a customer. I've been trying for over a month before I decided to write this review. I believe the product works well as described in their tutorials. They also have live tutorials during the week. I could not get to those live tutorials to ask the questions, due to my work schedule. They do not appear to care about specific customers technical issues.
