Those message are about the Maven repository, not about SVN. Such messages are often temporary and can usual be ignored. However, they might indicate that you need to set up your proxy settings at Window->Preferences->General->Network Connections.
It is not clear what your problems with SVN are. Note that MyEclipse doesn’t provide the SVN plugin but we can sometimes help with specific problems. However, you may get better support at the appropriate forum for your SVN plug-in (Subclipse or Subversive).
If you can provide more information, we may be able to provide some support but please be specific about which plug-in you are using, which release of MyEclipse you have installed and exactly what the problem is. Screenshots would be useful. Also, if you clear the error log, try your actions again and then attach the resulting error log (the .log file in the .metadata folder of your workspace), that may help us track down the problem.
Just to repeat, you may get better SVN support from a forum that is specific to your SVN plugin. Here is a Subclipse forum. Here is a Subversive forum.
