Buying Shares = Runtime Crash

[predatus2]

I downloaded the NoAi version to play against wright and admiral competitors.
My start is very good, but their building skills are fenomenal and they demolish me.
Sometimes, I try to buy shares from the weakest competitors to have a chance against the best players, but I receive a Runtime Crash. Is this normal?

This is not normal. However, I cannot reproduce this, when exactly does it happen? Does it happen everytime you buy a share, or just when you take over the company, or randomly while buying a share?

I can buy shares from any of my competitors, but in the moment I try to take over their companies (the last 25 procents), the games crashes.

I played the NoAI version a month a go and buyed several of my competitors without the game crashing, but when I tried to buy others, the crash appeared. I deleted the game and I moved on.
Yesterday, I wanted to play some tycoon . But now, I can't buy any of them.
