hey there
been to the same trouble as you are now , last year after one month ,i upgraded to windows 10 ,it also kept crashing ,now i'm back to windows8 and i can download from everyone but 30% of users who are trying to upload from me ,their uploads are either failed aborted,refused,annulated the rest of the users can upload without problems
i suggest that you do the same as me go back to windows 8 and it'll probably work ,well it worked for me , and most other software that worked well under win 8 win 7 even vista and xp had also the same problem crashing under win 10 i mean
go back to win7 or win 8 ,that's the best advice i can give you
