This is the screen shot



I'm using 2.4.2 and trying to add moltoclix and probux plugins via File menu and "load site" option but it doesn't response. After that result like that screen shot. There is also no error message . I am able to add these plugins to software that 2.3 version thus I confirmed ur saying. However I tried to cut and paste this files to "sites" folder (even "old" folder in it) for 2.4.2 but anything changes... (

Has anyone got an opinion ?
