would suggest you contact the CAA before trying to get your instructor..( i am assuming that you gat him to sigh your logbook for each of the night flights )..
there probably is a length of time they will accept taking all into consideration...including how long it has been since you flew conventional aircraft etc ..etc...
i would think they will want you if not to so it all again.. or perhaps to do a few hours and get signed off before they will entertail it..
i assume yours is a national licence not JAA...and so i do'nt know your proficiency requirements...to keep it alive before carrying pax again but in any event that does not arise..
contact the CAA and see what they say...
in my experience they are most helpful...
good luck..
