Solid Rocks crashes Max 2011

Hello, I recently installed solid rocks on my 3ds max 2011 64bits running on windows 7, I successfully made some test renders, but once I restarted max it just crashed on the startup, I tried rebooting my system but the bug just didn't fix. Once I uninstalled solid rocks, max stop crashing, so, I know solid rocks was causing the trouble. Any idea to fix this? how can I install this tool without making max to crash? Thanks in advance.
