You're right, plugins, icons and themes (dlls) has been lost but hopefully, not your data and configuration !
My mistake, sorry !
Your previous profile would be still available here:
Apps\Miranda\Data\settings\<name of your previous profile>
In order to solve the issue, you have to copy again the plugins dll you used before (I hope you remind them...) and copy them into their corresponding folders :
Apps\Miranda\App\Miranda\Icons
Apps\Miranda\App\Miranda\Plugins
For instance, if you used tabsrmm plugin, you have to copy it like following :
- tabsrmm_icons.dll and toolbar_icons.dll into Icons folder
- tabsrmm.dll into Plugins folder
Usually, the way to install them is described in a file inside the plugin zip package (readme.txt)
Unfortunatelly, I can't fix the lks before tomorrow evening...
