Installing TF2 troubles

I'm currently trying to install tf2 however everytime it gets to 90% download, it fails. I have tried deleting the folder, clearing my cache, repairing my library, and changing my download region, but nothing works. I love team fortress 2 and really want it to work. However, it's being incredibly difficult. If anyone has figured out a way around this issue, I'd really appreciate a step by step solution.
