SR stoped working Max 2015

Worked a bit with active shade view,
since then I cannot start SR anymore. Did a reinstall of vray and SR latest versions.
Still it doenst boot up and hangs at "SolidRock is starting...."
Please help

Hi !
Thanks for the reply, meanwhile, is there anything I can do to get it started again?
I would love to post an Attachment to show the problem. But the function on the forum doesnt work.
Nevertheless, when I Start SR. The GUI gets initialized at fist but the dialog "SolidRocks is starting..." doenst dissapear. and the Method Dropdown remains emtpy. If you press the dropdown button or hit the render button. A MAXScript Rollot Handler Exception is thrown with the message:
"--Unknown protperty: "qmc_earlyTermination_amount" in V_Ray_Adv_3_30_04:V_Vray_Adv_3_30_04"
Is this the issue with the new version of vray?
Do I only need to install the old vray version?
Thanks
Tim
