phpbb to vb3 connection to source server failed

[theoperative]

I know it has been asked a million times but I got this error.

Connection to source server failed. Check username and password.

I want to know if the sourcepassword can be changed? Honestly, I don't know what else to do..I've deleted and re uploaded 3 times and I still get that damn message I have even tried other passwords I use, here are my settings on Impexconfig the board works fine its just this.

targetdatabasetype = mysql
targetserver = localhost
targetuser = "lopezvic_forums"
targetpassword = "********"
targetdatabase = lopezvic_forums
targettableprefix =


; mysql OR mssql
sourcedatabasetype = mysql
sourceserver = localhost
sourceuser = "lopezvic_phpb1"
sourcepassword = "*********"
sourcedatabase = lopezvic_phpb1
sourcetableprefix = phpbb_



This is the error received
