MSN Messenger won't connect after CCleaner

Please help me. After running CCleaner in my notebook and desktop, MSN Messenger can't connect. I'm using WinXP and MSN Messenger 7.5.0324.

I've tried all the tips from MS (http://help.msn.com/(ZmlsdGVyPURIX0ZSRUUmcHJvamVjdD1tZXNzZW5nZXJ3MTBfNSZtYXJrZXQ9ZXMtRVMmY3U9JnRtdD0ma2M9JmZvcm1hdD0=)/Help.aspx?filter=DH_FREE&querytype=keyword&query=80048820&fs=1)but I can't connect, nevertheless.

Please don't send me to the winapp.ini topic (http://forum.ccleaner.com/index.php?showtopic=2747&hl=regkey2) that key is not in my register.

Thanks!

A little off topic, but MSN MESSENGER SUCKS!

Try this:

Open MSN Messenger > Goto Tools > Options > Connection > then click Start on the Connection TroubleShooter

Hopefully it will let you know where the problem is, If not try Re-Installing MSN and see if that fixes the issue.
