Home network filesharing - Access denied!

I've been trying to figure this out for a week now. No matter what I try I cant seem to copy/move/delete files from one of the pcs on my home network although I can browse to it. I get the dialog box:

File Access Denied
You need permission to perform this action.

I'm using windows 7 on 2 home pcs and 1 laptop. I had filesharing working flawlessly on the network before I upgraded one of my pcs and now that is the only inaccessible one. My settings:

All PCs on HOME homegroup with same homegroup password
file and print sharing is on
password protected sharing is off
Trying to share C:\Downloads
Permissions for 'everyone' set to full control.
Firewall disabled

Ive tried taking ownership/auditing and adding 'full control' to the groups 'Everyone', 'Authenticated Users' and 'Administrators'
I've tried uninstalling my firewall
I've tried reinstalling the lan driver with the latest one from the motherboard website
I've tried a clean install of windows 7 and still no luck.
homegroup diagnostic finds nothing wrong.

Any help appreciated!
