how to error? lolwut? grammar is the difference between knowing your **** and knowing you're ****. i understand English is probably not your first language but still. also this is the section where you post downloadable mods not where you post that you installed them wrong.
To get rid of the black screen goto .minecraft if u know hoe and delete the bin folder then run minecraft, it will automatically come back all fresh with no black screen just you will not have any mods
