When I log into Runescape with Swiftkit, all the ping areas in the "select world" sections show n/a. The only way I can correct this is by deleting and reinstalling Swiftkit every time I want to play. Can anyone give me a more permanet solution? Thanks very much!

SwiftKit has no control over anything displayed on the runescape website, but as we're such nice people I'll give you some suggestions on what to do;

 

First and foremost; Try reinstalling java ( feel free to follow the guide here http://kb.swiftkit.net/question-runescape-wont-load.html on how to install the right version)

If this doens't resolve it, check your Antivirus, it is quite common that Link Scanner modules in antivirus software messes with things such as packet lookups in java.

Thank you very much nice person. I have done as you suggested and it seems to be working!!
