Lync 2013 WAC Issue "Sorry, PowerPoint Web App Ran into a problem opening this presentation."

Hello Readers,
Currently we are facing Powerpoint presentation issues for Lync 2013 users internal as well as external.
IM, A/V , Polling working fine
Tried scenarios are :

Lync 2010 users to Lync 2013 users: showing presentation at both sides (internal & external)

Lync 2013 users to Lync 2010 users: not showing presentation on Lync 2013 client but showing at Lync 2010 client (internal & external)

Lync 2013 users to Lync 2013 users: not showing presentation at both sides (internal & external)

Below is the error we get

NOTE : This issue occurs due to several errors as I mentioned in below link. Every time whenever you get above error, you simply need to delete the cache from below path shown in the red box.

After I made several changes in Farm & IISARR rules everything was working fine like Powerpoint presentation sharing internal as well as external.
But after 2 days I was again started getting above error while I was testing sharing Powerpoint presentation between external Lync 13 users.
This issue occurs due to Caching of powerpoint files on Office Web Apps server below path as shown:

Special Thanks to Anthony who helped me to resolve this issue.
First stop the Office Web Apps Service on Web apps server & Simply go to the above path & delete or move the data to other path if you need.
Now start the Office Web Apps Service & try to share the PowerPoint presentation files which we get errors.
Now it should work fine without any issues.
Mine Powerpoint presentation sharing is working fine.
