I think we would all like it up yesterday 
Unfortunately Stardock are a smallish company and thus have a smaller IT department than say your Microsofts of this world 
Things are slowly coming back up as they work on each one, but there are many systems and they all interact with each other. Things like the integrated skin browsers went back up last week along with these forums. Activation was back very quickly as that impacts customers and the main website was back up shortly afterwards I believe.
I am personally not aware of anything thats not coming back up.
There have been posts on the Stardock Reddit group including one from the CEO with information.
I am unsure why you would uninstall the software though? It works just fine, should activate just fine and in fact an update for one of the apps is coming out later today. Just because IT are busy doesn't mean the rest of the company have been sitting around doing nothing.
