TurboCAD LTE includes TurboCAD LTE and TurboCAD LTE Pro. You should note that this product was originally called DoubleCAD XT Pro. We offer free assistance troubleshooting unexpected software errors via our online support system.  Please email us at support@imsidesign.com with your  support question.  IMSI Design currently supports owners of version 9

Why aren’t older versions supported?  The system requirements for older software are out of date, so the working environment cannot be duplicated by our technical support team. In most cases, issues are resolved by upgrading, and you are strongly encouraged to do so.  To request an upgrade quote, send an email to support@imsidesign.com
