Home group access denied

Hello,

I used the function to clean network passwords on my notebook and I can't access anymore to the folders shared by others pcs in my home lan.

Now win7 asks for a network password that doesn't exist. How can I solve this problem?

I've already tried to quit from the home group and join again but it didn't fix anything.

Thank you for your help.

The Network password is the code that the first computer in the homegroup makes the first time. If you don't know this code I believe you may need to remake the Home Group. I would suggest unchecking "network passwords" in ccleaner.
