Hi Danny,
Something else you may want to try is to 'reattach' Quik Link to Excel. This actually has to be done for each workbook. The specific directions for doing this is on pages 1-14 and 1-15 of the manual, but baasically it would mean:
1) Opening the workbook with Excel's File Open (so the DNK file is not accessed).
2) Edit the link (Edit | Links) and change the source to the quiklink.xla file inthe directory where Quik Link is installed.
3) Recreate your link to Accpac (Quik Link | Link Define).
4) Recalculate the workbook (F9 function key)
5) Save with Quik Link's File Save
Lastly, if you were to create a brand new workbook, can you duplicate the error messages?
