Steam Servers Too Busy to handle your request

[del]Yup, this error’s back on my side. A couple days ago my Garry’s Mod gcf corrupted and I had to delete it to be able to start Steam.
Now when I try to install GMod, it drops a Steam Servers Too Busy error. When using the GMod Beta gcf as a placeholder, it tries to validate, drops the error again and says it’s been 100% validated.
I’ve tried reinstalling steam and changing download region, nothing worked.
What do?[/del]

Welp, deleting game content worked.
