Several days ago after downloading exp ML version for 5d3 with support of 10/12bit raw i faced a problem that i cant switch type and number of AF points to chose. I have only one posotion - 1 point af - that is impossible to switch. After that I uninstalled ML and tried clean 1.2.3, 1.3.4 and 1.3.6 but switching firmwares didnt help at all. I think it s quite easy to solve but im new to ML so i do not know how and hope you can help me. Also tried to attach some pictures of mine menu here but i simply do not know how to do it on forums, so sorry for that to =)
Restore cam's factory settings (including C.Fn) and retry. Warniing: If you have any custom picture styles installed you have to reinstall them.
