VT Power window problem

Hey, long time lurker first time poster.
Ive come across a problem on my driver side window where yesterday it went down but would not go back up, then kind of just dropped down.
Ive taken the door trim off and have seen a guy with a similar problem saying it was most like due to the plastic slider thing being stuffed.
Anyway at the moment im kind of stuck with this issue (as seen in the picture) where im guessing the window has to be sitting on that thing thats up against it?
How do i go about getting it back under the window as theres no give in it and i dont want to be scratching the tint anymore than i already have :S/
Appreciate any help,
Cheers
