Warnings during the use of Spectre

Hi~ I am kinda a newbie to Cadence. Don't laugh at me if my questions are stupid :)

I am using version 5.1.0, and IBM design kits.

Some warnings come up when I start up cadence. 

1. Startup:
*WARNING* No user triggers registered for viewType schematic.
*WARNING* No user triggers registered for viewType schematicSymbol.
*WARNING* No user triggers registered for viewType maskLayout.
What do those mean? How to get rid of this?

2. When I open the schematic, click any simulation tool, either Analog environment,or ADS dynamic link . It shows:

*WARNING* ERROR (LM -30): license server ("") does not support feature "34510" (run 'lic_error -30' for more information)
*WARNING* ERROR (LM -30): license server ("") does not support feature"Analog_Design_Environment_L" (run 'lic_error -30' for more information)

I check my licenses from "Options", I can only "check out" ("95210     Virtuoso(R) Analog Design Environment XL"), but not ( "34510     Virtuoso(R) Analog Design Environment" . 

So is this a serious problem? I can still run simulations.

3.While doing simulation, the following show up:

spectre (ver. 5.10.41.071008 -- 10 Jul 2008).

So, is it because of my version of spectre doesn't support AHDL? How to fix this?

Thanks!!!
