Try to import PTS again if you have your pts wallet backup.

I restore my windows system and forgot to backup my wallet. and I recover some backup file from c:\.
Luckily, I found a backup json file . but this json file is backup before I import PTS into BTS.
and after import this json file ,I could only get a little XTS.
I have tried wallet_regenerate_keys, but it can't get all of my XTS back.
Is there some method to get all of my XTS ?
