URGENT need help with PLC5 and wonderware comms

[plcsavvy]

I am using an Allen-Bradley PLC5 connected to wonderware via RSLINX. I am using DDE data exchange.
Each time I try to run wonderware intouch v7.0 viewer, I receive a message under rslinx DDE comms event log.
The message is as follows;
"affected item list 1035 type read invalid file type".
I am not sure if 1035 in the affected item list is item number 1035. Can someone please explain what this means as I have not encountered this before.

best regards, PLCsavvy
