Screen Saver settings not saving

I installed a third-party screen saver on my Windows 7 Pro x64.
I set the custom 10% size, but after a reboot it reverts back to 50%.
On all my other PCs running Windows 7 Ult x64 it runs fine.
Could this be a Windows Permissions issue?
I have never had a Pro version of Windows before (always Ultimate), is this a common problem?

Anyone got any ideas?

P.S.: The screen saver is: fliqlo (clock)

Update: A facebook contact figured it out, so I'll post it here for others.

Step 1: Place screen saver .scr file on Desktop
Step 2: Take ownership of the .scr (There is the hard way, and the easy way)
I installed: http://cdn3.howtogeek.com/wp-content...eOwnership.zip which added Take Ownership to the context menu.
Step 3: Right-click .scr and install.
Done!
