here's the easy way to do it (and this one is in english) based on how i'm going to assume he uploaded the file.
i'm going to assume its just a folder with no file extension. it may be a zipped folder. here's what to do.
step 1: unzip/unrar the folder/file
step 2: now you should have a folder. click on it.
if there is one folder inside that has a name that seems similar to a league kind of thing (dankfile, mlb2004, dank, etc), click on that. if you see a bunch of files with no recognizable extension (it might be .dat for all i know. regardless, they most likely won't have a real icon), then everything is unzipped. you want to go back to that folder (where you were before clicking on it and seeing the files/folders normally within a league file) and add .lg to the end of it.
if the folder you're left with after unzipping has nothing inside it but the folders/files of a normal league file (such as almanac, league news box, whatever), then re-name that folder with a .lg at the end of it.
the reason it doesn't work is because the folder isn't a "league" folder. it needs the .lg ending on it. and it needs to be in the ootp 6.12/6.5 (or 2006, if you're using that game) directory. For 2006, i believe it goes in the "saves" folder
