Hammer Stops loading a vmf at 5%

Any ideas as to the solution? Shouldn’t have anything to do with the vmf as I havn’t added anything in the past 3 days. It loaded fine yesterday and I didn’t add anything, any ideas as to the solution?

Restart hammer/Steam/Source SDK?

Try and follow this tutorial.

If it returns some sort of error, your VMF may be corrupt. Just grab a backup copy from C:/HammerAutosave
