SMI Excel Add-In "Add accounts" dialog box not appearing

Hello.

I have a client who is having a bit of an issue with their SMI (linked to a Sage 100 ERP) via the Add Reports function in the Add-In tab in Excel.


Another user on an older machine has no issue with the functionality.


However, when this user tries to add in new GL accounts via the option the dialog box for adding the accounts does not appear. Let me go over some points with this:


- 32 bit WIndows 7 machine, running with Admin Priv

-Sage 2013 and the newest version of SMI (which is registered)

-Excel 2007.

-All other functionality works: Pivots, Change Accounting Period, Drill down, ect. It is simply the "Add Accounts"

-No dialog box appears, however, it acts like something will be popping up, with a brief spinning window, and then nothing occurs.

-I have tried putting the Solver Add-in in and out because I saw a potential fix somewhere else for this, to no avail. Have also tried running Compatability Mode for Excel

So basically, the Excel add-in from SMI isn't able to bring up the add accounts dialog box for one user and we cannot figure out why, and why only that function. Has anyone run into this, or does anyone know a way to reinstall the add-ins without needing to re-register SMI?
