Why can't I transfer from External HD to Mac?

Hello. My Macbook Pro Mid 2012 13" can’t read my files from my external hard drive (WD My Passport Ultra 1TB) neither can I transfer from external to Mac. I’ll attach here the message from the laptop when I try to open it. The format is on MAC Extended (Journaled). I opened the external using TransMac from Windows 3 days ago but I really did not open any of the files I just checked if they are still in the external. D:

Here's the link for the "message" https://drive.google.com/file/d/0B1sB4SP...
