Ok, now it's fixed :)
Thanks a lot for the tips!

PHP Code:

CreateFilePath(String:buffer[], maxlength)
{
    static String:game[32];
    static String:version[32];
    decl String:date[32];
    decl String:temp[128];
    
    // game name
    if (strlen(game) == 0)
    {
        GetGameFolderName(game, sizeof(game));
    }
    
    // game version
    if (strlen(version) == 0)
    {
        new Handle:file = OpenFile("steam.inf", "r");
        ReadFileLine(file, temp, sizeof(temp));
        CloseHandle(file);
        TrimString(temp);
        new int;
        int = FindCharInString(temp, '=', false);
        StrCat(version, sizeof(version), temp[int]);
        ReplaceString(version, sizeof(version), "=", "v");
        ReplaceString(version, sizeof(version), ".", "");
    }
    
    // date & time
    FormatTime(date, sizeof(date), NULL_STRING);
    ReplaceString(date, sizeof(date), "/", "_");
    ReplaceString(date, sizeof(date), " - ", "_");
    ReplaceString(date, sizeof(date), ":", "_");
    ReplaceString(date, sizeof(date), " ", "_");
    
    // path
    BuildPath(Path_SM, temp, sizeof(temp), "logs\\%s_%s_%s.txt", game, version, date);
    
    // return
    strcopy(buffer, maxlength, temp);
}
