java.lang.UnsupportedClassVersionError: net/darkhax/bookshelf/asm/BookshelfLoadi ngPlugin : Unsupported major.minor version 52.0

That mod isn't compatible with your java version. Most likely you need to either upgrade to java 8, or downgrade to java 7. (whichever one of those you don't have is probably the one you need)

I made my own shader pack, by the way.
