Xara Slideshow Widget issue

[Dencuga]

Hello everyone.
I am not everyday user of XWD. It means that I make some web sites from time to time ... it can be 6-7 months between jobs.
So I used once really nice and usefull Xara Slideshow Widget from Online Content Catalog - Photo Slideshows and Galleries.
It worked fine, just like I wanted to work.
Well, after some time, I tried to use this widget on some other site, but I receive message "Sign in to Xara hosting ..." with
e-mail and password required fileds. When I typed my login data, I receive answer: Login denied. Login failed ..."
Ok, maybe I forgot my password, so I tried to recover with pass-recovering procedure ... but with no success.
So my question is, did I miss something regarding this wigdet ?
Does anybody use it ? Is it functional anymore ?
Does anbody have advice, what to do ?

Thank you guys !
