I am running V2.06. I purchased a Full node and a standard weeks ago.  From day 1, the full node has not worked. The box disconnects, locks up, and hasn't moved past 15%; numerous connections have been refused.  I've reflashed the SD card, performed a format on the SSD drive innumerable times, and even placed two node configuration lines provided by Futurebit support (dbcache=128 and maxmempool=128); both did nothing.  I went through all my firewall settings, as I have a Firewall router, and placed the full node IP address in emergency mode, which essentially opens all ports and disables all existing rules and policies that did not work.  I connected it directly to my ISP via WIFI, that did not work.  At this point, I feel like I'm doing FutureBit's job, and I didn't pay $1,700 to play helpdesk support on my own.  I also tried to reflash the SD card to version 2.05, as some stated that the version was much more stable, but that did not work.

The most disappointing experience was that I purchased over $1,700 of equipment and have not received one response from Future Bit for days, except one email, which took almost 4 days to respond.  I am incredibly frustrated with the equipment and lack of support.
