Firstly I'd like to thank you for providing the scripts. They're helpful as fuck.
It's odd, I delete my cache. It redownloads the cache as you'd expect, extracts the zips and reaches 100% on that and gets to dreamscapes 'loading client - this wont take long' screen. And then.. It nulls.
If I click 'OK' on the confirmation box, it restarts the procedure of downloading the cache and installing. Which of course, takes us to the null again.
Not sure if anyone else is experiencing this, but I thought I'd document it.
