I'm trying to install jME2 but I keep getting this error:
Checkout operation for 'http://jmonkeyengine.googlecode.com/svn/trunk' failed.
svn: REPORT request failed on '/svn/!svn/vcc/default'
svn: Processing REPORT request response failed: XML document structures must start and end within the same entity. (/svn/!svn/vcc/default)
see if this short vid helps

it never happend to me, but i read that some virus scanners can cause some problems:

I'll try it again while watching the video…though I'm using a mac. No virus scanners here
It appears at the end of the process by the way
