Help With Texture Packs

Hi, Mantis here, I recently received a new laptop (Dell Inspiron 15 7000) and everything is working fine.
However, upon attempting to log onto a Wynncraft server, I get the following message: Internal Exception: java.lang.IllelgalArgumentException: Parameter 'directory' is not a directory
I believe it is a problem with the texture pack that is causing this issue. When I set packs to prompt instead of enabled, my client only shut down when I clicked accept texture pack.
I can log onto the hub without any problems.

 

Try going into your .minecraft folder and adding a new folder called "server-resource-packs" if one does not exist already.

 

It worked! Thanks!
