Not really. Some refractors wont come to focus either, depending on what you use to image with. You may have to use extension tubes on the focuser draw tube or shorten the telescope tube to move the focuser further up. Also, it is becoming more obvious that refractors can have as much coma as reflectors so a field flattener will be required also, and this then can change your focus point too.
Pick a scope and camera type to use, do whatever mods are required and go from there. Don't stress, enjoy the hobby and learn as you go, it takes a while to get it right!!
I am also a bit concerned that you have a low profile focuser and have moved the mirror up the tube and it still wont focus. Are you in an Astro Society where you could get some help from one of the imagers in the group?
