You are lucky, it is a standard round-robin. Look what could be the next time

To help with your results:
Enter your players into SwissSys.
Make pairings (Pairings/Pair-Next-Round or F5)
Set to Round-robin.
Go to Pairing rules... (the same window).
Click on FIDE defaults but (and) unckeck Random Lot Numbers for Round-Robin.
OK. OK.
Now you should get a window "Assing Lot Numbers". Carefully assign the numbers accordingly to your crosstable.
OK.
You'll get a swiss-type crosstable .
Then go Pairings/Round-Robin-Pair-Table, where players must be in the same order as in your crosstable. Enter as Chris wrote (work with a mouse or a keyboard).
Hope it helps and does not confuse completely
