I've noticed that last 4-5 versions have increasingly got more unstable/reliable.
The latest one makes SEOtools so unreliable I've started building my own python scripts to do things I've relied on SEOtools for 4+ years.
If anyone has a tip on how to fix this... I'd appreciate it. Slamming 'calculate sheet' 5-10 times gets me most of the data I want, but I question its accuracy. 
If I let it sit on '#GETTING_DATA' it never finishes.
Hi,
We recently fixed a major bug related to the #GETTING_DATA idle cells. Which version are you using?
What other unstable/unreliable situations are you experiencing?
v7.0.11 (from the title)
The instability involves pulling large data-sets from majestic (like 500,000+ backlinks). It doesn't finish anymore, just crashes excel or only pulls a portion of the data-set.
Other issues I've had involves checking live backlinks with a similar outcome to the above example.
Yeah, should have seen that 
Can you try 7.0.13:

I didn't realize I had an older version. So far .13 isn't giving me the same problems.
