How do I install Mavericks from the App Store if I erased my HD?
My mbp has been acting funny and slow, and I think I may have had some corrupted files. I have my computer backed up to time machine, and additionally I saved all my important files, photos etc to the external HD before I began. Then I erased my HD. Everything I read indicated that since I had installed mavericks previously (and legitimately), I would be able to do so again from disk utility after I finished erasing the HD so long as I had a working Internet connection. Well, I do, but now when I click "Reinstall OS X" I get a screen with Mavericks and then an error message saying, "this is not a supported method of installing the operating system/ please run Install OS X Mavericks.app that you downloaded from the app store." But I erased my hard drive! I really don't want to use my time machine backup because I'm worried some of my files are corrupted, and wouldn't that just put me back in the exact same position?
For the record, it's a late 2010 MBP that originally had Snow Leopard. My boyfriend upgraded it to Mavericks for me a few weeks ago.
MacBook Pro, OS X Mavericks (10.9.2)
