Getting error -10011 in filemaker when using AS in script step

Question

Hi,
I hope someone can help. I have had this script working before but am just making the transition from FM 6 to 7 and have to update the scripts.
I am gathering info using FM script steps and AS scripts from the backdoor of iTunes. When I create a new record i am getting "Data being accessed by another user,script or transaction". (-10011) several times when i attempt to pass the info back into the record in the FM database. I get the error as i attempt to write the data i want back into the current FM db record. Here below is one field being written back and it generates this error once. Other subsequent scripts for other fields generate the same error. I am using this AS at that point:
tell application "FileMaker Pro"
set the_source to item 1 of (field "Source_number" of database "CD database" as list)
end tell
if the_source ≠ 0 then
tell application "iTunes"
set return_value to 1
set disk_name to name of audio CD playlist 1 of source (the_source as number) -- assumes is the first CD
set disk_name to my ConvertOwnerToString(disk_name)
set junk to class of disk_name
if (disk_name is "") or (disk_name is "Untitled Audio Disc") then
-- connect
set disk_name to get title
end if
end tell
tell application "FileMaker Pro"
set cell "Title" of current record of window 1 of database "CD database" to (disk_name) as text
end tell
end if
The error happens at the "set cell" line 3 up from the bottom.
When i invoke this routine separately i do not get any errors and it works fine !!
Any ideas ? No other users logged on, no other apps use this file.
Thanks

Try temporarily turning off all your firewall and antivirus software until the download has completed.
