Cannot build corps

Hello,
I play just for few real life days but i cant find way to build corporations... I have many free workers, money and 6 production plants... but when I set a corporation to build, it just delay every month again and again. It last more than 6 months to and nothing is done yet. Could someone tell me what to do?
Thank for your responses!

The only time this happens to me is if I don't have enough unemployed people, the game will delay the corporation being created. I looked at your country and you have plenty of available workers. I have no idea why this is happening. Maybe Andy can shed some light?

This is several days ago, I am sorry.

There are no corporations under construction.
I see a new corporation in one of the two countries.

I see messages about shortages.
Please check your materials in the trading menu.

also, read your newspaper.
I saw the shortages messages and also a corporation was closed some months ago.
