You are quite close. Put those 4 letters to one side. From the middle of the left of the two horizontal places you should have a separate 3 letter run. From the middle of the right of the two horizontal places you can vertically line up these three vwith your other 4.
From the first two letters of the starting place (if you have that worked out) you can get the 5th letter in your 4 letter sequence. From the 5th and 6th of the left vertical place you can then get a fourth letter in your three letter row.
Remember that non alphabetical runs are very likely to be in the top three rows of the grid as the bottom couple tend to be the unused, more unusual letters. If you try the lined up 4 and 5 letter rows above and below each other and cycle through the 5 possible options for the left hand letter in each row, something thematic should hopefully jump out at you.
