IntelliPrint Error?

I am using IntelliPrint to generate a report. I try to add the @Unique function to an existing formula in a field in IntelliPrint and I get the following error when I save.

Error:

Access violation at address 0360A724 in module ‘nTPrint.DLL’. Write of address 06B85000.

Notes closes and I have to reboot to get back into Notes?
