I am not sure why your having problems with DBPro crashing. It could be any number of things. I can't diagnose this for you at this point.
Below are some ways you may use to approach your bitmap/text problem...
Example 1: Using Bitmap 0 outside of a loop
sync on:sync rate 0
load bitmap "filename",0
ink rgb(255,255,255),0
set text size 30
center text screen width(),screen height(),"Your Text Here"
sync
suspend for key
end
Example 2: Using bitmap 1 copied to screen (bitmap 0) in a loop
sync on:sync rate 0
load bitmap "filename",1
ink rgb(255,255,255),0
set text size 30
do
copy bitmap 1,0
center text screen width(),screen height(),"Your Text Here"
sync
loop
Example 3: Using paste image in a loop
sync on:sync rate 0
load image "filename",1
ink rgb(255,255,255),0
set text size 30
do
paste image 1,0,0
center text screen width(),screen height(),"Your Text Here"
sync
loop
