{
_verincre++;
string filen = fi1.Name.Substring(0, fi1.Name.Length - fi1.Extension.Length);
PathNew = fi1.DirectoryName + filen + " ver " + _verincre.ToString() + fi1.Extension;

Your directory path was not correct. Use the following code:
public string RenameTitles(string _titlerename)
{
        string PathNew = null;
        FileInfo fi1 = new FileInfo(_titlerename);
        if (fi1.Exists)
        {
               _verincre++;
                string filen = Path.GetFileNameWithoutExtension(fi1.Name);
                PathNew = fi1.DirectoryName + "\\" + filen + " ver " + _verincre.ToString() + fi1.Extension;
                FileInfo fi2 = new FileInfo(PathNew);
                if (fi2.Exists)
                {
                    RenameTitles(_titlerename);
                }
            }
        return PathNew;
}
