I automatically upgraded bm-custom-login from 1.3 to 1.4 and as a result lost both the custom "my-login-bkg-tile.psd" file in bm-custom-login\image-templates folder, and the "login-bkg-tile.jpg" in the bm-custom-login\images folder. This COMPLETELY defeats the purpose of the plugin -- to keep the custom logo while upgrading the software. I lost ~ 2 hours of work that went in creation of "my-login-bkg-tile.psd" file.
Thumbs down.
