If you've installed the 43.0330 Lacerte update, and Windows is completely updated, reinstall the Lacerte update by either

• Tools/ Lacerte Updates and choose "reapply Updates" from the dialogue box that says you are on the most current version. 
• in ToolHub,  "Install"  -> "Websetup/Force"  (reinstalls the update)

Different option:

• In Tool Hub:   "Program" -> "Reset Display"  (which is a go-to for us if having problems with displaying forms/worksheets)
