I forgot to mention that you should also check your QRASP directory, which contains the tables Quik Reports for Windows uses for reading the data. The above directory will be found on the drive where all of your Accpac Plus programs are, and you should look for files of the type qrt*.qrw. If none of these exist, then you should reinstall Quik Reports for Windows to refresh the tables. You may want to reinstall anyway...
Also edit the crw.ini file, located in the C:\windows directory, and look for the 'Accpac Path' setting, near the bottom of the file. The drive letter should be where your Accpac Plus programs are, otherwise there may be a problem. If the information is incorrect, you can change it here and save it.
