Ok just no report if you left unsaved. Seems I left yesterday without saving.
But still no report is not good.

For all versions before v1.24.1:

Let's say you disable "Save on Exit"
You play the game, and save on 1/1901.
You play until 1903 and turn off the game.
You load your save game, it's 1/1901. However the reports data is from 1903! You have the incorrect information!

Reports are generated at the end of the end to turn processing. The 1/1901 reports are gone, you overwrote them when you ended the turn during your last play. In order to prevent the user from getting incorrect data from future dates of their unsaved play, the game will not let you open the reports if the current generated reports do not match the current game turn.

To generate a new batch of reports, end the turn.

Well, it's either no reports, or reports from your unsaved game. Either way the reports would be useless. I would rather tell the user, "Hey, you don't have reports, here is why." Instead of displaying completely incorrect reports.

Yeah if there is no other way its ok.

I have that problem now, but for me the game crashes after i finish the turn. Had that window that said that the report does not match the month (what is also strange since i know that i saved the game beforehand) and that i should end the turn. Happens with all the saves now Any suggestions? Or do i have to throw away the saves?

If you're using Antivirus software, you will need to disable it. Verify the game cache https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335 and then whitelist these files before trying the game again: http://wiki.gearcity.info/doku.php?id=troubleshooting:antivirus

If it still happens after that, you may not have write privileges to the directory: http://wiki.gearcity.info/doku.php?id=troubleshooting:runasadmin
