Remove blank line - SED

HI, I have this list of apps like so:

Uninstall DivX for
Install Flash Player 8

There's that one blank line between "" and "". How do I remove that blank line? I've already tried "sed '/^$/d'" but it didn't work.
# 2  
Then the line isn't really blank.

Maybe something like grep -v '[A-Za-z0-9.,:;!?]' (or the equivalent in sed) could help remove it?
# 3  

That did the trick, thanks Smilie

sed '/^.$/d' file

please test on more data.
# 5  
Same problem, that space still stays there...
# 6  
We speculate that it's a DOS carriage return; if so, you might want to convert the whole file to Unix line ending conventions because otherwise, the problem will continue to haunt you whenever you need to match something at end of line, etc. See if dos2unix or your local equivalent would help (search these forums if you can't find a good command installed locally).
# 7  
So how do I convert the file to UNIX line endings? And if anyone is wondering where I got the weird space from, it was written to the app by an AppleScript script. I told it to write a "return" to the file, following some text. The return should have put a normal line break in there, which it did, but it certainly is an unmanipulatable break.
