problems hitting renderbutton

hi jerome
sorry posted this in the public section. you can delete it there if you want...
have some troubles here:
max 2011 design x64 win7
everything went ok till now.
I had to install Autodesk Design Rewiev and it bothered me not having installed Microsoft Visual C++ Redist 2008 sp1. but it was. unistalled those, installed new. no luck. and so on. I found on a forum the tip just to unistall every Visual C++ 200x also with Windows Installer Clean Up Utility and then try again. Autodesk Design Rewiev setup then will download the apropriate versions of Visual C++. This worked.
Now installed is:
- Microsoft Visual C++ 2005 Redistributable
- Microsoft Visual C++ 2008 Redistributable x64 9.0.30729.4148
- Microsoft Visual C++ 2008 Redistributable x86 9.0.30729.4148

(there can be installed different versions side by side for some reason, earlier were)

so now the problem. after a fresh max start everything works great. but after some working the solidrocks render button won't work. error messages:

-- Error occurred in refreshmini(); filename: C:Program FilesAutodesk3ds Max Design 2011UIMacroScriptsSolidRocksB09x.mse; position: 249941; line: 984

can you help me?
thanks

yes last build.
yes after restart same problems.
the stunning thing is that it just happens after some work in the file.
I had some troubles installing things. had adobe cs5 cs4 update problems so I spent an afternoon cleaning and reeinstalling. I don't think it touched any 3ds max related installation. The problem occured after that so I think it could have something to do with that. I know that max needs visual c++ which I completly removed as descibed and let install again through design review installer. couln't that be a problem? before, I had different versions of visual c++ (one from max, one from autocad and so on... strange).

no 2010 here. jumped from 9 to 11. stability problems
