SWOS 2020 - bug reports

You guys seem to have fixed it with the last update. Great job, running smoothly now!

The last update correct the issue. Thanks!

I've won the Polish League and Polish Cup in my career, but did not qualify to any of euro cups, any idea why?

Hi all.
2 days ago I was playing the game, then I finished my matches and closed it, all good.
After some hours I re-opened it and since then whenever I click on RUN SWOS  2020 it says "Invalid Filename", same as other users reported weeks ago. 
I opened the DLC manager to check something and it spams error windows saying 

"Cannot create file "....\1995_96 - European Championship Edition_preview.7z". Cannot access the file because it is being used by another process"



I tried to open this .7z file in the folder ...\SWOS 2020\dlc\teamdb  and it says it's impossible to open it.
Ah, yesterday I downloaded the latest SWOS executable file (v. 6.4.3.9) but that Invalid Filename error persists.
Thanks for the help
