Hello.

I recently downloaded Minecraft onto my Windows 8 laptop, and it works just great. I play in 1.7.10 usually (since the newer versions seem to lag immensely) and it works perfectly fine.
However, when I loaded Forge and tried booting up the game with mods installed, it would merely show me the following error message:

I have tried to diagnose the issue myself with no result. I have finally resigned to the conclusion that I need special help to get the game working right. Is there anybody out there who can make sense of this and tell me what I need to do?

Did I install a mod intended for 1.8? I currently only have Forge installed. No actual mods. I did have a few before, but I've since removed them to test if they were the issue, and yet the crashing continues.

I can assure you sir that my mods folder is completely empty. Yet when I attempt to load the game, I get the following message.

I do notice that this message is a bit different from the last one, however I cannot tell exactly how considering that I do not possess very much intelligence. But I do know that a mod beside Forge is not the issue anymore. It may have been at first, but the issue was not resolved by removing the mods.

Aha. I believe I know how to reverse the damage I have done from here.

Thank you for your patience, and I apologize for taking up so much of your time with my obvious incompetence. I hope the rest of your day is not like these last few minutes have been.

Thank you again.
