Overwrote Index Files while attempting WordPress Install

I accidentally overwrote the index files while installing WordPress. I am currently attempting a restore but would like a Plan B. Would appreciate options. I am familiar with the compatibility issues with elgg and WordPress but thought I had a solution. Appreciate any suggestions. Thank you.
