Problems building corps

Hi. I am having problems building new corps in my country. I have purchased production plants, and while the corporations say they will be finished in the next month, it has been about 4 days now, and no corps have been built. Any help would be appreciated.

For some reason this game has gone equity finance. So if your in the red on cash you can't build companies
buy goods on direct trading and sell on market
no debt allowed on main entity

I don't have any debt though. I have lots of money, or does your monthly earning balance matter as well?
