FCKEditor WYSIWYG Editor

I'm having trouble uploading pdf's larger than 2 MB using FckEditors default filebrowser. Could it be my connection having a restriction or is there a upload setting I need to tweak to make it work? I upload pdf's mostly from work rather frequently (2 - 6 a week).

I struggle to upload pdf's from work, but it does not seem that I can replicate the problem from home.

I'm working on a site with an audience that will want to use a WYSIWYG Editor for content updates. Currently I'm trying to set up FCKEditor for the site. Everything looks good except there are some options in the FontFormat dropdown that I would like to remove. I've tried following the instructions on the FCKEditor site <a href="http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/Configuration/Configuration_File>here, but changes to FCKConfig.FontFormats in fckconfig.js aren't getting applied to the site editor.
