Checking Resources Error

My computer keeps on checking recourses in the loading screen. I followed the steps for this error with the pack check.

It gave me this error:


C:\Program Files (x86)\Grinding Gear Games\Path of Exile>packcheck content.ggpk
Checking pack file content.ggpk...

C:\Program Files (x86)\Grinding Gear Games\Path of Exile>^A
☺ wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.

(Translation: is not recognised as an intern or extern command, program or batchdocument)

C:\Program Files (x86)\Grinding Gear Games\Path of Exile>

But it still does not work.
