Upload processing timed out

I am new here to upload my very first project, its been since noon and more than 4 hours with failed uploading error.

As per the screenshot, everytime, it throws the same error.

My main file is about 35 MB and have 5 screenshot images. Followed all instructions as per Envato suggestions. Archived by WINRAR with .zip extension.

I even uploaded via FTP and all files show on upload page.

But the form is not being processed and hence finding it frustrated. I even submitted ticket and header said, they would take 5 days to revert back.

Hence, I thought to drop in here for an expert suggestions. Anything specific I need to follow?
