Can't re-open converted project saved in V3.1


I successfully converted a v3.0 project to v3.1 and worked on it for a day. I saved it at the end of the day and closed ccpn. Today, I attempted to re-open the project and received the following pop up message: “Cannot rename module HC. Name already taken.” The terminal trace is pasted below.

Thanks in advance for any help you can give.

Hi Mary,

this sounds as though there is some kind of clash between module names. It is unclear to me what the repercussions of this error are. Does the project close again of its own accord/not really open? Or does it simply not restore some of the SpectrumDisplays? The easiest thing is probably if you send us your project and we can take a quick look at it.
