Thank you for trying Webclipse. The CodeLive and JSJet validation are part of Pro features which can be accessed for free for upto any 8 days per month. If you want unlimited access to the Pro features every day then you will have to upgrade to a paid plan.
Please refer to these links for more details about the Pro and Free features in Webclipse :
