Format Word Document - Remove timestamps on individual lines

[lbeck]

I'm wanting to edit a 70 page Word document. It has time on every-other-line. Format for the time is **:** like 11:30.. What I'd like to do is to remove the time line completely and the resulting white space. I can do a search for the colon but cannot do a replace with del del or backspaces. Then I'd like to remove the white spaces left by the removed time.
