Nhentai Label error

[GoogleCodeExporter]

Describe your actions to reproduce an issue:
1. Using nhentai.net listing
2. Tried to download first multiple galleries, then only single galleries.
3. Each time received these errors:

20:36:09 nhentai.net: @thread.execute():

What result do you expect? What result did you get?
E:Gallery download.
R:Error
Which version of program and OS do you use?
2.1.0.134 windows 7

Additional Note: I attempted to download galleries that grabber had previously 
been able to download only to receive the same errors as well.
Tried downloading a gallery from g.e.hentai and it worked perfectly.
Is this a problem on grabbers side or did nhentai change the way their code 
works?
