So i was installing a mod, it was actually a mod installer called the hens 101x-ray mod installer. The video--> installed and then went to check it out on my minecraft. I opened the launcher and all that stuff. But then something weird happened, the installer wasn't 1.7.9 like it should have been.It was 1.4.4 and i was logged out. I know you can change versions but i didn't do anything. I checked my minecraft folder and everything was all right, My saves, resource packs and all.Along with all the files.So i wen't back to the Mod installer and un-installed the mod and checked my minecraft and still it was 1.4.4;and i was still logged out. I Decided to re install the 1.7.9 launcher from the minecraft website but the same thing happened. I know MY mojang username and password. But i'm afraid that if i log in something weird will happen. Will i loose stuff in my world? Will it update and can i change back to 1.7.9? Thanks!
Added (1). oh yeah and the installer was 1.7.9 and up to date, so i don't know why my launcher turned in to 1.4.4
