I have raised this problem before, without any response. So I'll try again...

Everytime I start or exit MindManager 2018 on Windows 10 I get the following error: "sv-SE. Value cannot be null. Parameter name: o" (see image below)



Why does this error appear everytime? Can it be fixed? It's really annoying... Is it a setting/flag somewhere that is wrong?

ust to be sure... are you on the latest version? 18.2.109.
You can find it inder File => help
It has some minor bugs solved and better performance.

If you are not. do the check for updates.
(be sure to close your MindManger and MS Office apps before installing.

After installation you will see it uses your License key and all settings are as you left it.
