I tried to reload a backup when I was trying to clean up some of my (useless) mods. But, when I saved the backup, it didn't save any of the minecraft.jar files. So I lost Forge. I tried to reinstall Forge, but for some reason it won't start up when I start minecraft.

 

I have tried installing it with/without modloader (with/without modloader mp). I also moved the Forge files that were saved to another folder in order to give forge a fresh start. unfortunately, nothing seems to work.

 

I could really use some help as I can't figure out why it is not working.

Are you doing it all manually, or with a patcher? What archiver are you using? Operating system? What's the error you're receiving if any? Please provide a stack trace and any other error reports in spoilers...

 

Also, you should be doing it both without ModLoader and ModLoaderMP. Forge has both built into it now. You just install Forge and delete META-INF.

I am imputing it manually. Not sure what you mean for archiver, but I have 7zip to view my jar files and other programs for the other file types. My op is Windows 7 and there is no error message, nor any stack trace appearing.

 

Well 'does not work' is not really descriptive enough to help.  We need the log, and if the game crashes at all at any point (even if no error message) then there is always a stack trace printed to the terminal and/or log, we need that too.

Thank you for clarifying

 

Unfortunately, 'does not work' is as accurate as I can be. when I enter the game, the normal Mojang title appears and then enters the normal Minecraft title screen. the vanilla Minecraft  title screen. I have no "Mods" button, no info on the bottom of the screen, and I'm getting no logs. It's as if forge isn't even installed.

That's the most critical information you could have given. X]

 

Try again with these steps:

[*]Force Update Minecraft to clean it up

[*]Download Recommended or Latest Forge build

[*]Open minecraft.jar using your favorite archiver (7-Zip should be fine)

[*]Open Forge.zip (try to be sure to open it with the same archiver)

[*]Drag and drop all files from Forge.zip into the minecraft.jar (be sure to not accidentally place it in a folder)

[*]Delete META-INF Folder within minecraft.jar

[*]Play before installing any other mod to be sure it worked

 

If the above steps lead you to the same problem, try making sure your archiver is up to date and/or try a different one. (Such as WinRAR)

You might also try MultiMC as well.

OH THANK YOU!!! it is now working fine (before I have installed mods). I'll reply later if anything occurs while I put in more mods....

Be sure to thank the person (Zero) that helped you by clicking "Thank You" in the upper-right corner of his post. 

I did, as well as you. Almost everything is working, but I'm sure NEI is not for this forum.

Again thank you both!
