Can't install Garageband Instruments and Apple Loops 1.0 on OS Mavericks
Today I decided to download (one more time) the Garageband Instruments update and I waited for like 5 hours+ and when it was almost finishing the download it appeared that I was already installed. So I went to Garageband to check out the new instruments and nothing was there, it was just like before the update and when I click on a new instrument to try it out, this message appears just like before download this:
And when I go to the Mac App Store to download it again this is what I get:
And after clicking the Update and/or the Update All button, it turns gray and says it is installed, it doesn't load or anything, I just click and then appears just like in the image below:
My MacBook Pro is currently running the latest version of OS Mavericks and the latest Garageband ver. which is 6.0.5. I really need to use those new Instruments and can't figure out how to fix this... Thanks in advance to whoever helps me.
Side note: I already tried restarting/turning it on and off and it didn't work
MacBook Pro, OS X Mavericks (10.9.1)
