Problem in saving fields input

Hi, I found your plugin interesting so I used it in my project. I am using the latest version 2.0.8. From past few days, whenever I save any field, the data does not get saved in it. I had to do it many times, finally, I created a new field, the same problem again. Why is this happening so? I am also seeing many other members complaining about this plugin. One member also told about losing $50. Look, people use this plugin and payment gateway runs here, real money transactions are happening, I hope you understand the situation. I have used this in my project, the reputation of my business and my client’s business depends here. Can you please look into these issues. I don’t want to lose client and money, nobody does. Previously I had asked a query 2 weeks ago, still unanswered. Is this plugin trustworthy, what should I do?
