I am using SAP/Sybase PowerDesigner 16.5. Have used it on and off for years. Whilst I haven't opened it for a few months, I suddenly find I cannot update an existing model (I can open it OK); Nor can I create a new Model (PDM or LDM - and probably nothing else either) I have tried both opening a blank workspace, and create a new model; and open an existing model. In simple terms, it appears like I am reduced to read-only status.
My question is this: Is this a known issue, and how to resolve?
I am running 64bit Windows 7 Professional (v6.1 SP1) and Office 2010 - neither has changed although we download and install regular Windows updates.We have not downloaded any updates to PowerDesigner since downloading and installing 16.5 about May last year. I have tried uninstalling PowerDesigner and re-installing.
