cPickle and open('w') on Windows

So I just spent a long time processing and writing out files for a project I'm working on. The files contain objects pickled with cPickle. Now I'm trying to load the pickled files and I'm running into the problem: "Can't import module ...". The thing is, I can import the module directly from the python prompt just fine.

I started noticing that my code had the problem reading the file (getting EOF error) and I noted that I was reading it with open('file','r'). Others noted that I need to specify that it's a binary file. I don't get the EOF error anymore, but now I'm getting this error.

It seems to me that I've screwed up the writing of my files initially by writing out with 'w' and not 'wb'.

The question I have is, is there a way to process the binary file and fix what 'w' changed? Possibly by searching for line returns and changing them (which is what I think the big difference is between 'w' and 'wb' on Windows).

Any help doing this would be amazing, as otherwise I will have lost weeks of work. Thanks.
