So today was working away bopping my head away to some electro swing and coding away when out of no where power went out for a few seconds. No biggie I'll just loose 5 mins of work, CTRL + S every 5 mins anyways. Now I open up my new master page I see the following;

Only other post on the internet about this is

and I cannot copy the first column of numbers or anything at all since when I try to paste it pastes nothing??

If I do not get this file back I'll be loosing a lot of days of work. (should of used TFS) but its legacy website that I am just doing a little renovation on!

Any ideas?
