try without optifine

I didn't use optifine. I sent the wrong log so it looks like i did (I didn't)but i updated what the actual log is just a minute ago

What exactly did you do?

I exported it using eclipse into an archive file then I emailed it to myself to use on my current computer and then imported it using "existing project into workspace"

This will not work at all.

Use a Git repo. If you must use a zip file, copy the files that are not in the .gitignore into the zip file only. Then set up the workspace like normal, as described in the Docs.

so I will have to make the zip again just not select the .gitignore?

No. Make a zip and select everything that is not listed in the .gitignore.

Really this is the gradle wrapper files, the build.gradle, the gralde.properties and your src folder (and anything else you might want to keep, but definitely not the build or .gradle folders). Then import the project as normal.

But seriously, just use Git.

ok I'll try that then. Thanks
