I got to downloading just as soon as I realized Cakewalk was going under.
I spent several hours at home downloading as many setup files and instruments as possible, then went to work and set about downloading the rest to my work computer. Took me the best part of a day to get everything. So glad I did now. I'm sure I've missed something, like Rapture packs or some other add on, but I think I got all the important stuff, thank goodness.
It's pretty traumatic for users who put off installing every single feature of Sonar so as not to clog up their computers (such as me) to just be cut off from the products that they bought. Especially as many of these fx and plug-ins will work in other DAWs.
If (and I hope it is only an if) Gibson has pulled the plug on the servers, it's a really ****ty way to end a ****ty situation. I'll give them the benefit of the doubt for a few days, and hope the servers come back on line.
