Thank you very much, najrut,
This time the files worked ok... but I'm sorry to be the bringer of bad news.
I installed everything as instructed, started typing a word (tried several times with different words) and the software stops working. Error message is "GoldenDict dictionary lookup program has stopped working
A problem caused the program to stop working correctly. Windows will close the program and notify if a solution is available."
FYI, I did not have a previous version of slovacukt/Goldendict in this computer. I'm using Windows 8.
I hope this is a minor issue that can be fixed easily. I'll keep trying.
Best regards and thanks again.
