I've now fixed the problem by updating the file Utils.R (which was responsible) to include the script for the function betaPar2 (which I use to compute the parameters of a Beta distribution under a constrain specified by the user in terms of the mode and the upper value that is reasonable to assume).
I think the very first version of the file I've put on the website was actually OK (ie it included the required function), but then I must have messed it up during one of the updates.
