SVN (with connector) doesn't work after/before installing Scala plugin eclipse

SVN (with connector) doesn't work after/before installing Scala plugin
eclipse

So, im little newbie with eclipse but this is really weird issue.
So i install my Eclipse Indigo, then i installed SVN, after restaring i
got question about SVN Connector (i choose SVNKit 1.7.10). Everythink was
working. Then i install Groovy plugin, still working. Then from official
site i install Scala plugin, and then suddenly after restarting eclipse my
SVN didnt work. It was installed etc, but it didnt work. So i figure out,
i will install Scala plugin first. Then i installed SVN and after
restaring i didnt even get this 'message' about svn connector, so i
installed it manualy. Still doesn't work.
This is my issue, meaby someone met this kind of "bug"? Thanks in advance
for an answer and sorry for my bad english.
