Yes, sorry, I don't have time right now to look at your files in detail.

According to the help for 'append', your horizontal/vertical thing is 
supported in principle. ("The appended data may take the form of either 
additional observations on series already present in the dataset, and/or 
new series.") AFAICS, "new series" is equivalent to your "horizontal", 
and "additional obs" == "vertical".

Note the condition given in the help: "In the case of adding series, 
compatibility requires either (a) that the number of observations for 
the new data equals that for the current data, or (b) that the new data 
carries clear observation information so that gretl can work out how to 
place the values."
Is that the case for your files?

Also, using an explicit 'setobs' command after loading the first dataset 
might possibly help.

good luck,
