My problem is the same. I cannot open the business. It tells me to select and manage small business through the small business settings - but the lot was built on small business lot in the first place. I play on PC. I removed all mods and tried selling the business - it gave me 240 simoleans for a much more expensive business building and lot [done on separate home lot] - BUT it tells me I am still the registered business owner - but the business cannot open. So I bulldosed the lot, and put it back from the gallery - now it tells me I am still already the registered owner, but cannot open the business, as it is not the registered business on that lot. Help.
