The file I'm trying to decompile is from SABNZBD+ 0.4.6.  I modified
downloader.py late 2008 and I accidentally lost it after I compiled it.  I
include a unmodified downloader.py and my compiled\modified downloader.pyo.

Please fix this as soon as possible!

I ATTECHED FILES!!!!!!!!!!1
DOWNLOAD THEM TO HELP ME!!

I include a unmodified downloader.py and my compiled\modified downloader.pyo.

To semiblocked:

Hello, see you again,haha.

I have fix this problem,but another problem occured. 

To fix this problem,you can add the following grammer in p_grammer function in 
Parser.py:
whilestmt ::= SETUP_LOOP 
stmts JUMP_IF_FALSE POP_TOP
stmts_opt JUMP_ABSOLUTE COME_FROM

The reason is :
for a while loop, while 1 : is a loop that never stopped if no break, so python
compiler optimized this as 'SETUP_LOOP <then some other statements>', but there 
is
none corresponding grammer to handle this in current unpyc.

If you fix this problem ,please let me know. And hope you can fix the left other
problems and tell how do you fix them.

We can talk more about python in future.
