So I have tried downloading the source files to Liferay in order to modify the plugins but every time I try to open the zip file it says "Windows cannot open the folder.
The Compressed (zipped) Folder 'C:\...\liferay-ce-portal-src-7.0-ga3-...zip' is invalid.
I''m thinking the download is corrupt so I was wondering if anyone at liferay could fix this.
You should check the hash (MD5 of SHA-1) of the file and compare it against the hash published on sourceforge.net to make sure the file you downloaded is correct. If the download keeps failing, you can also try switching to a different mirror.
