Lisa just so it may help someone in the future who runs into this, let me state what the actual fix was.
Through debugging tools we found when you clicked Convert in Company Maintenance, the SY_CompanyConversion_ui.pvc file in Links was loading SY234_CompanyConversion_ui.pvc program in SY folder. This is a DSD overload program presumably to convert DSD enhancements. We found it was tied to an eBiz extended soln. Since client didn't use it anymore, instead of requesting an updated version from DSD it made more sense to just rename SY_CompanyConversion_ui.pvc in Links.
