For those who haven't tried to get support until now, let me share the following feedback I just sent:
I spent 2 1/2 hours speaking to three different levels of "support", twice they remotely took over my pc. The 3rd level informed me that I needed a case specialist and had two choices; either hold on to the call that had already taken up my day or "schedule' a call back that could come at any time over the next two days between 1pm and 7pm NYtime. I stayed put for 15 minutes and hung up. I will never call your support line again, nor will I renew the product.
All of this with a known error 0X80004005, n5,nC0. Just hope that your installation doesn't go sideways and you need some help.
