"Alias(kindle in my case)" can't be opened because the original item can't be found

I am not a computer genius so will appreciate any help someone can give me to be able to access my kindle. I connect via usb and the kindle shows up in my finder but when I try click on it to access, I get the error message "Kindle can't be opened because the original item can't be found". I have no idea how to fix this and it all started with upgrading my software.
