2 issues:

Address Book--For some reason, I can no longer view my contacts. It's not
that I don't have it checked on the "view" list. They still auto-fill when
I'm composing a message, and I can view them when I select it from the
"tools" menu, but they don't appear in the lower right corner. Just an empty
box that says "they're no contacts to view". I've looked through every
setting I can think of and can't seem to find anything I might have switched.

Fowarded Messages--I can view any and all attachment just fine, except for a
forwarded message. The .eml file type is no longer recognized, and I can't
assign OE to open it (even by selecting it from the list). I did install
Mozilla Thunderbird on a friend's recommendation as a better email program,
but subsequently removed it after I realized I wasn't too fond of it. When I
went back to OE, that's when I noticed the problem (FYI the address book
problem above was prior to installing that software). I've tried to fix the
registry but it was to no avail, and I tried reinstalling IE 7 completely but
that didn't work either.

Any suggestions would be greatly appreciated.
