BlazeCraft_1234

Ok so the other day I was getting ready to play some Minecraft and I put my mods on it and this popped up Failed to download file, the file contents differ from what was expected. Name: jna-4.4.0.jar URL: https://libraries.minecraft.net/net/java/dev/jna/jna/4.4.0/jna-4.4.0.jar Filename on disk: jna-4.4.0.jar Path: C:\Users\Blaze\AppData\Roaming\.minecraft\libraries\net\java\dev\jna\jna\4.4.0\jna-4.4.0.jar Exists: File and so I tried playing again and the same thing popped up and so I took out all of my mods and it still popped up it didn't crash my game because it won't even start and I re downloaded forge many times and it happens with 1.12.2. The other part of the story is that my 1.7.10 wont work either it pops up and says Failed to download file, the file contents differ from what was expected. Name: jopt-simple-4.5.jar URL: https://libraries.minecraft.net/net/sf/jopt-simple/jopt-simple/4.5/jopt-simple-4.5.jar Filename on disk: jopt-simple-4.5.jar Path: C:\Users\Blaze\AppData\Roaming\.minecraft\libraries\net\sf\jopt-simple\jopt-simple\4.5\jopt-simple-4.5.jar Exists: File and I have done the same thing for here as well. My Minecraft won't respond unless I go into my task manager and end the Minecraft launcher (32) task for some reason. Please help!!!!

Well it crashed with the secret rooms mod and then i cant get back on so i dont know what to do bc it was working fine before and now it doesnt.

Every time i try and join back onto my world it crashes and then says The game crashed whilst unexpected error Error: java.lang.StackOverflowError: Unexpected error And then I go to view the crash report and it says all this And I don't know what to do. Please help me I wanna continue building my bunker with my mods.. P.S. Sorry the whole thing is really big I didn't know what to do with it and didn't know where to put this message.
