I just gotr a new computer. I downloaded WinRar and CBR. I can read CBRs that I download but I can no longer create CBR files. I used to do this by highlighting a set of JPGs and creating a RAR, then changing the .rar file extension to .cbr. This no longer works. When I change the .rar to .cbr and open it, the .cbr is blank. I can convert it back to .rar and everything is there.
