Problem with setting textfield text. Possibly CS4 to CS5.5 issue?

Hello,

I have another post on here today about trying to set a textfield’s text in AS2.

I have been working on this problem all day. I am beginning to wonder if it is due to the fact that the fla was authored with CS4, maybe even CS3 and now I am trying to use it in CS5.5

Any advice? Very frustrated here.
