You're welcome. 
It can be a challenge to get a toe-hold with this kind of puzzle.
One approach to is to use graph paper for your answers & look for crosses.  
If you can get a couple of 12s that would help.  Also small groups such 7s, 6s, & 5s can help.
Less common letters, such as B, C, G, H, P, U, V, Y,  are handy for crosses. 
There are two Ks & an X, but they are unchecked.
The preamble also gives hints re uncommon answers, though 10A isn't really.
Hope that's of some help.
 I'll try to post the solution in a couple of days.  Have to get my ar*e in gear & install a new printer / scanner.
