As I wrote in a previous answer, you should have opened a case for the "blue led disfunction". So the best thing to do now is to ask the support for any information about the status of this case. As far as I know, this is something which should be manageable over-there in the US. But I am (one of) the developer(s) of the Origin *software*, not the *hardware* so I may be wrong.
Concerning the "lock up" of Origin when you turn some knobs it may be a hardware or a software problem, or both. To decide wether it is one or the other (or both...) we need the informations I listed in the same previous answer (preset which is loaded, Origin connection to external midi equipments, To a host via the USB plug, MIDI activity, serial number, firmware version...). And you should open a case with the support for these "lock up" bugs. This is the best way to manage that kind of problem.
As a matter of fact, it is the only way for you to be sure that these problems will be followed up by the the support.
Also it's really much much easier for me to track a case number (because I have the tool for that) than to dig into old posts in the forum.
