ray widgets' installation

after i started using my site, some ray widgests (my prsence, profile music, video) all uninstalled themselves. when i now try to install those widgets, i get this error:

                                   cannot open file

                             'presence/install/install.xml'

any idea what i can do??

well - before opening admin area - go to widgets xml folder - and set permissions for necessary files to 666 and to files folder to 777

After you will open admin area - you won't need to make any installation any more
