Hello Arne:

I'm sorry to hear that you're having trouble with custom tracks. 
Example 8 has a note next to it:

NOTE: Paste operations on some platforms will replace tabs with spaces, 
which will result in an error when the GFF track is uploaded. If you 
encounter an error when loading a GFF track, check that the data lines 
contain tabs rather than spaces.

This is most likely the problem.  The link for example 8, which you 
included in your email, works for me, as does saving the data from that 
link into a text file and uploading it.

Try copy/pasting from the version of example 8 from the link:
http://genome.ucsc.edu/goldenPath/help/ct_example8.txt

Instead of copy/pasting the version from:
http://genome.ucsc.edu/goldenPath/help/customTrack.html#EXAMPLE8

I hope this works for you.  Please don't hesitate to contact us again if 
you require further assistance.
