oops! Serialize()RMF ERROR..please help!

[Dillyto666]

Before this error occured, Ive been mapping without any errors. One day I opened Valve Hammer 3.5 and my map showed the folowing error:
[Oops! Serialize()RMF v2.2 tried to load a file v0.0. Aborting.]

Then I clicked Ok and it didn't open the darn map!

My prefabs are ok, no changes, as I sayd the map opened fine before.
The map is mine and Ive ben using only the 3.5 version of Valve Hammer while I was making it and I havent changed anything in the editor options.
I have no idea whats wrong. Ive been mapping for Half-Life by the way..
Also the map is saved an .rmf format, not .map.

Find the back up file and load it. It might not be as done as the one you want to open but at least it's going to work.

Already done that
It might be corrupted by a virus, dont you think?
...right, it may be?
Damn how I hate hackers and viruses - god, If i see a hacker, Im gonna cut his b*ls out!...sorry about that, emotional explosion.
