This may help in why the binding broke, but may not be the immediate solution to getting it back on the window. However, if you have continued problems then this method may be the best bet. I keep spraying on silicone spray to avoid doing any major work, but it will be a problem in the future for me, so eventually I will use this thread to fix my problem....
Good Luck!
