Can't Load File

Hello! Attempting to load a Yahoo Groups archive from Web Archive by using the browser version of ReplayWeb.Page - however, during the upload process, the load will get stuck between 10% and 40%. A friend of mine also tried the same file and is encountering the same issue. The file is 1.00GB and is a .warc.gz file - extracting the file and uploading the .warc seems to get stuck before 1%. No errors appear during either occasion.
