How to fix Remote Desktop Connection Manager 2.7 decrypt error pop up window issue

I recently upgraded Remote Desktop Connection Manager (RDCMan) 2.2 to version 2.7. When I open the .rdg file, I get this giant popup window:

Because the file has so many hosts with encrypted password, the size of the error window exceed the screen. I couldn’t even get to the “ok” button.
To fix this issue, we can remove the <password> </password> pair from the .rdg file.
1) You may want to backup it, actually you should make a copy before open the .rdg file with version 2.7.
2) Open the .rdg file with Notepad++. Press ctrl+h to open the “Replace” popup window.
---Find what:<password>.*</password>
---Replace with: null
---Search mode: Regular expression

3) Click “Replace All” button and save the file.
4) Open it with RDCMan 2.7. no popup window anymore.
However, you will have to re-enter your password for these hosts.
