Ok, try directly from terminal as ROOT (just copy this commands to terminal:
For tweak F:

Code:

cp -f /home/user/MyDocs/.N9QTweakBackup/usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style/libsysuid-screenlock-nokia.css /usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style

and press Enter...

For tweak Q:

Code:

cp -f /home/user/MyDocs/.N9QTweakBackup/usr/share/themes/base/meegotouch/call-ui/style/call-ui.css /usr/share/themes/base/meegotouch/call-ui/style

and press Enter...

Reboot your device..

If this still not work, that mean you probably have another theme/app installed, and restore backup not work.. And I don't know how to help you..
