Carrousell given an error

Hi, I been using carrousell from Jet Pack since the beginning of my website and I have tons of pictures in there, all of them in groups of 8 or 10 pictures each gallery

I disabled carrousell just very temporarily to see what happened – I had another plugin which I never used called “Gallery NextGen”

Then I checked my website and when I looked at the pictures, everything works but now it shows this horrible message above the pictures “Carrousel has been deactivated because another plugin took over the shortcut – gallery

Like I say, apart from this horrible message over the pictures everything works as usual

I then fully deactivated the other plugin NextGen with the hopes that everything would be back to normal but it hasnt

You can see the problem yourself by looking for example here:

http://www.torreplaya.es/propiedades/ref-16205

them you will see several black tabs within that page and you will need to just press in “fotos” = “pictures”

I will really appreciated any help – I will not like having to redo all the galleries as I have at least 50 of them already – thanks so much in advance
