That message is coming from the Microsoft JET engine, which is what Tableau uses to access CSV files.
The JET messages are notoriously bad - very often the message very explicitly says something very different from what the real problem is. For example, I see that particular message all the time and the usual reason is that the file name includes two dots - JET's little brain can't count beyond one dot.
That isn't your problem, though, but it will be something vaguely similar - "the table does not exist" basically means "something bad happened".
I tried creating a file with exactly your filename and copied in your sample data and it opened fine for me in Tableau 8.
So my guess is that it is something to do with language settings - my laptop is set up in English. My guess is that you have German locale settings on your machine, and that even with Tableau set to English, as you have in the screenshot, something like the hyphens in the file name or the use of commas as field separators is confusing it (though your screenshot shows you have selected commas, so that looks OK). Or maybe the character set isn't UTF-8?
Hope that helps.
I'm sure Tableau support will be able to set you right on this - they will be well versed in all of JET's annoying little quirks.
your answer set me on the right track. Indeed Tableau seemed to have a problem with the commas. I took a second look at that JET error message and albeit somewhat cryptically it mentions that the field delimiter is equal to the decimal delimiter (probably set by the German language operating system somewhere as you guessed correctly).
Although untrue for the file in question (all decimal points are in fact . (dots), making the file perfectly valid on an English language machine), when replacing the commas with a semicolon I got the file into Tableau all right.
