[racket] frustrated with error message

With regards to the error below, we are using dr Scheme v4.2 (I know  
its an old version but the tech guys at my school take months to test  
every upgrade that we ask for) and we are running windows 7.

I copied the entire error message below again:

>> insert-file in text%  error loading file (read from file failed)   
>> === context ===



Thanks for your help
