IGuy43

I have now saved my worlds, but completely uninstalled and reinstalled minecraft, deleting all files and data with the exception of my world saves. I can enter the game's main menu, but once i select a world/create a new one, the game sits at this loading screen:

I tried it and nothing downloads. It just sends me to this page:

By the way, I also may have downloaded an unofficial version of OptiFine. I had troubles downloading the files from the original site; I reached the downloads page and passed the AdFly page, but nothing ever downloaded, and I was instead redirected to the website. I also do not know how to address this issue.

I believe that is it, if not, please let me know how to retrieve said information.

I have attempted to fix this problem, but I can't seem to resolve the issues. I have downloaded and installed the latest version of Optfine, but the game still crashes every time I attempt to launch it.

I may have an outdated version of optifine running now that you mention it...

Every time I attempt to run minecraft 11.1.2 I receive the following message: The game crashed whilst initializing game Error: java.lang.VerifyError: Inconsistent stackmap frames at branch target 21 As well as the following: The game crashed whilst initializing game Error: java.lang.VerifyError: Bad return type

It successfully downloaded, but now my game is crashing after I have selected the Forge profile from the launcher. I cannot access the game menu.

This pops up

I have typed this into the command prompt, but it says it is unable to access the jarfile.

Sorry, didn't realize that

Is there another step?

Done.

yes the "Open the folder containing the downloaded file in Windows..." part your post. To reiterate, I have a very low knowledge regarding technological terms.

I downloaded the .jar file, but I don't understand the second command.

Found it

How would I go about doing that, by the way I am very new to both Minecraft and Forge so I probably don't know how to do much of anything.

The same problem arises when I run the .2 version.

I have had this problem before with previous downloads of Forge, but withy the 1.11.1 download, the message "These libaries failed to download. Try again. net.minecraftforge:MercuriusUpdater:1.11.1" and I don't know how to address this issue. Please help me.

I'm sorry about my lack of knowledge when it comes to technical terminology. What exactly am I supposed to insert into the command prompt?

And how would I do that?

I followed the feed's instructions but it still won't let me download. By the way I am very new to minecraft and I am trying to download basic mods to improve my computer's performance. I have never attempted to download Forge before.
