Let's Control It

Hi,
I had a PC with win7 and a portable setup of the Arduino 1.6.11 IDE.
I moved that to my new Win 10 PC, but now I get these messages over and over again.

(Ivalid library)Ongeldige bibliotheek gevonden in D:\Tools\Arduino Sketches\Schetsboek\libraries\pubsubclient: D:\Tools\Arduino Sketches\Schetsboek\libraries\pubsubclient
(Invalid labrary) Ongeldige bibliotheek gevonden in D:\Tools\Arduino Sketches\Schetsboek\libraries\TLS2561: D:\Tools\Arduino Sketches\Schetsboek\libraries\TLS2561

How can I solve this?

Reinstall libs?

Thanks, that did the trick.
Some of the files I copied were corrupt. After copying the originial repositories, it was okay again.
