Unreliable and wipeout my database connection login credential

It used to be reliable, but after the last few updates it crash way too often to be use at work.
The UI is good but I cannot recommand this software to anyone at this moment.
A half year ago, I recommanded this software to few of my coworkers, they used to like it but now we all hate it.
Please fix the bugs and do some unit testing before you release the software.
This is a professional application, I expect it to behave like one.
How do you expect us to pay you $400 for the premium version when your most basic application fail to work.

After using it for almost 3 years, you wipeout all my databases connaction login credential.
Not sure because I am using the new Navicat Cloud, but this update wasted my time and make my work more difficult.
If it is not broken, DON’T try to fix it. Now you broke everything.
How do you expect anyone to buy your app for $150 when you wasted people time?

Third Review Update - Mar 15, 2016
You did it again, all the connection I saved is gone, and I have to set it up all again.
It is so annoying that you have to re-re-create the configuration after each time you update the app.
Wish I cant give it a 0 start.
