just downloaded yosemite and now cannot connect with wi-fi and can no longer scan from my HP all in one

after download a message said that " Flip for Mac " is not compatible and was moved to " Incompatible software folder ". Same for my Belkin Router monitor.

And then today I tried to scan a photograph to iPhoto and it would not scan even though I was able to update iPhoto with no problems. Has anyone out there experienced these problems and if so is there a fix. Thanks
