Thanks for attaching your Aiken file to your post. You do not say how that Aiken format file was prepared. Did you do it yourself? Did you get it from someone else? Which text editor did you use? Did you carefully check that its contents obey the Aiken format rules?
Here is the list of errors in that file:
1.- wrong use of a), b), etc. or a., b., c. etc. instead of A., B., C., etc. in some of your questions:
Which tab in the following dialog box would you use to add keywords for the document?
Identify on the following which tab contains the Word Count command?
A. Home Tab
B. Insert Tab
C. Page Layout Tab
D. References Tab
e. Mailings Tab
f. Review Tab
g. View Tab
2.- You cannot have "special formatting characters" within your question answers. I have removed 2 "problematic" questions from your file (see attached screenshot).
I am attaching a "cleaned-up" version of your file, which imports the remaining 88 questions correctly into a Moodle 1.9 or Moodle 2.0 question bank.
There remain a (small) number of symbols or "special characters" in the text of your questions which cannot be imported and displayed into a moodle question, or which have even dissappeared from your original file, e.g.:
When you see , what does this symbol mean?
A. You can rotate the picture.
B. You can move the picture.
C. You can resize the picture.
D. You can crop the picture.
Hope that helps,
