Cant install OS X Mavericks In Recovery Mode

Hey, guys!

So i recently decided to erase my IMac's hard drive as i had many many old files that was taking up so much space that it was easier to erase the hard drive and start over.

Anyways, i followed Apples guide to erasing a hard drive and followed all the steps correctly, but when i click on install OS X and enter my Apple ID and password, it will begin to download but then stop a few minuates later with the error "Cannot download OS X Mavericks, please try again from the purchases tab" Im not sure what to do, and im starting to get really worried. Please help!

Thanks!
