connection to svn+ssh svnserver not possible

Hello

I'm trying to connect to do our server with an existing local repository (currently using tortoisesvn)
Problem: whatever i try I get the error connection not possible.

I tried connecting via plink, but Smartsvn cannot find plink, i found an article (http://smartsvn.1697.x6.nabble.com/L...td3706070.html) but my version of smartsvn has no menu entry Repository?!?!?!?
(Using Version 7.5.4....) (see snapshot)

If I connect via public/private key, I get the error E210002: there was a problem ... and nothing more
(no idea what went wrong)

can somebody help me to get the system running?

regards
Norbert
