convertible top trouble!!
 

so about two days ago at work i was on lunch break so i decided to le the top down......it was about half way down when it made a loud popping sound....it went down the rest of the way fine and i didnt think much of it.....well i come back after break and try to put it up and the passenger side of the top is not going up.....the drivers side is going up but the passenger side is just kind of hanging....i got it up with the help of a friend guiding the passenger side and i haven tried putting it down since.....is it possible for it to come off track or something?ive never torn my car apart to see how the top works so i have no guess as to what broke here......if any one has any input that would be great.....i can take it to a shop to get fixed if need be but i would rather just do it myslef......thanks guys
