Program closes with big database

[Sycotone]

I tried out the program with a test user before starting the script with all the users. It worked just fine.
Afterwards I put in all the users data and tried to run the script again. After the first message and hitting ENTER as the [ANY KEY], the window just closes. In a previous issue (#41) you commented, that you should run it through a command prompt. The Error code now tells me, that the .csv file does not exist. But if I delete all users except the test user from the .csv file and save it the script runs completely fine again.
Do you have any idea how to fix this?

How big is the csv file?
Could you send a testfile here (with randomised data), so we can reproduce the error?

In what environment do you run the programm?
OS? From pre-built package or the script itself?

I found the solution for my problem. I don't know where I read it but someone said he had a problem with the german Umlauten aka ä, ö, ü. So I deleted all of them from the csv and then it worked.

I ran the program from the prebuild package on windows.
