Little square block characters in my database?

Hello All;
(Classic ASP / SQL Server 2005 Ent.)

I have seen these questions come in now and then.

I am using this

strMemo = replace(strMemo,vbCrLf,"<br />")

It just started happening today.
Everything was working fine up until now.

Below is one of my codes that WAS working that now, inserts this crazy little squares.

Cannot someone please tell me what in the world has happened?

Set frcmd=Server.CreateObject("ADODB.Command")
frcmd.ActiveConnection=objConn
strMemo = trim(request.Form("Memo"))
strMemo = trim(replace(strMemo,"'","''"))
strMemo = trim(replace(strMemo,vbCrLf,"<br />"))
MySiteID = int(request.Form("SiteID"))
MyMemID = int(request.Form("MemID"))
'if request.form("PWT") then
FriendsRequestSQL = "INSERT INTO MyForms (MemID, VisID, MyMemo) values (?,?,?)"
'response.Write FriendsRequestSQL & "<br / >"
'response.End()
frcmd.CommandText=FriendsRequestSQL
frcmd.Parameters.Append frcmd.CreateParameter("@MemID", adInteger,adParamInput, , MyMemID)
frcmd.Parameters.Append frcmd.CreateParameter("@VisID", adInteger,adParamInput, , MySiteID)
frcmd.Parameters.Append frcmd.CreateParameter("@MyMemo", adVarChar,adParamInput, 4000, strMemo)
frcmd.Execute
