Notepad++/Regular Expression to find line with same beginning, different ending

So, I've read a bit and found NotePad++ doesn't use "normal" regex (starting to think I'll just go back to SciTE), but here's my question:

I've got an exported list of data with some redundant data that I'm trying to clean up and convert into a good CSV for import into address books (migrating a Fax server solution, the old one is OOOOLD and so this is the best I can got for export).

The line I'm trying to remove from each entry group always starts

Entry: NAME ~

And then there is a 12 digit alphanumeric (is appears to be Hexadecimal) code that follows that is unique for each entry group. For a few entry groups there is a human-readable entry following "NAME", but these are few enough I can remove them manually, so matching them isn't a big chore.

So what I want to do is to find every line that begins with Entry: and select it all the way to the end of the line. Each entry in each group is on a separate line. Then I'll use Find & Replace to remove these lines from the list.

UPDATE: Input & Outpu

Entry: NAME ~00003193820
ShortName: ~00003193820
Owner: USRENAME
Name: John
FamilyName: John
DearName: John
Organisation: Acme 1 Corp
Via: FAX-ANY 1(555) 123-4567

Entry: NAME ~00003193820
ShortName: ~00003193820
Owner: USRENAME
Name: Sam
FamilyName: Sam
DearName: Sam
Organisation: Acme 2 LLC
Via: FAX-ANY 1(555) 890-1234

Here's two entry groups. I want to remove the lines beginning with "Entry:" from each and every group.
