Thanks for the provided minidump file. We've analysed it and It's related to this problem mentioned on our forum
:"We've recently found a bug in the RC 3.0.8 when using libraries downloaded with initial versions of Update Manager. Until we fix it, please download all your libraries again in the following way:
1) Delete all content under C:\Users\<your windows user>\AppData\Local\Itoo Software\RailClone Pro
2) Remove the following registry key (by using the regedit.exe or by the attached .reg file): HKEY_CURRENT_USER\Software\Itoo Software\Update Manager\Packages
3) Open the Update Manager (Start menu->Itoo Software->RailClone Pro->Update Manager), and download all necessary libraries.
That should fix the problem. It's not necessary to update the content on render nodes, because problem affects only the Library Browser.
We apologise for any inconvenience."
Hope that helps you and if there will be anything more we can help you with, please let us know. Have a great day.
