Delete your EZUpdaterstorage folder located in "YourDBfolder" <------ where the hell is that
-
Delete all plugins in the plugins folder located in "Plugins" folder in demonbuddy <---- did the trick for me cus i used the dll inside and copied to 2 sharpsvn.dll to folders 1 demonbuddy folder pluginfolder and 2nd copied the same sharpsvn.dll to the main demonbuddy folder.
i downloaded sharpsvn.zip and unzipped it to a folder whatever you like to name it.
that program to run that dll. sharpsvn 1.9ish 32bit would do the trick for you.
-Download SharpSVN 1.8009.3299 (1.8.9) SharpSvn [x86] ( https://sharpsvn.open.collab.net/servlets/ProjectProcess?pageID=3794 )
its a zip file extract it to a folder
done
now run demonbuddy with just the ezupdater plugin to start it and it will show you hes updating.
