File opening problem

User getting this error box every time she opens a file, whether it be a dgn or ips (Interplot). I am posting here due to the nature of the error message.

There has not  been anything done to her computer recently and once she clicks OK, it seems to enter the file and everything is working normally, but it is taking a very long time for this box to come up and then to finish entering the file after the error is dismissed.
