Hy,

I have just updated the LFS from K3 to K5 and all of my layouts gone. Pls help, I spent days to create them :S

Please keep a backup of your LFS.exe from 0.6K so you can easily go back if there are any problems.

I think the test patch doesn't affect the layout directory. But I use the .zip anyway so not sure (my .lyt's are still there).

I cant do anything, all of them gone -.-. I am so happy right now

Imagine your complete disk gone. Always backup.. (Although need to say that to myself also).

You have replays? Can retrieve them from replays. Otherwise I don't know.

I have nothing, just the setups. Replays, layouts and everything gone. All the same I will recreate them

Check your Recycle Bin.

It's a long shot but you could try:

Long shoot because - you can see that the folder structure does not affect any of the this you mention. The update itself couldn't break your items. I updated too and can view my own items.

Check if your stuff is present in K5 layout folders with explorer. I suspect you updated previously made completely fresh installation and forgot about it.
