Answer 1

It could be a problem of the standalone flexbuilder version. We tried to install subversive in flexbuilder and it also didn't work correct.

Answer 2

I've solved "!MESSAGE Conflict" in log by editing file:

 Adobe Flash Builder 4\plugins\com.adobe.flexbuilder.standalone_4.0.1.277662\plugin.xml

In this file next tag is unnecessary:

<actionSet
    description="%standaloneDescriptionNavigationActions"
    id="com.adobe.flexbuilder.standalone.navigate"
    label="%standalone.navigate.flex.navigation"
    visible="true">
     <action
           definitionId="org.eclipse.ui.navigate.openResource"
           label="%OpenWorkspaceFileAction.label"
           helpContextId="org.eclipse.ui.open_workspace_file_action_context"
           class="org.eclipse.ui.internal.ide.handlers.OpenResourceHandler"
           menubarPath="navigate/open.ext2"
           id="com.adobe.flexbuilder.standalone.navigate.OpenWorkspaceFile">
     </action>
  </actionSet>

This tag leads to duplicated "Open resource..." menu item. This duplication raises a conflict. Comment it (or remove) and start flash builder with clean option:

FlashBUilder.exe -clean
