B85M-D2V rev3.0 succesful SLIC but unsuccessful activation

[Mpalka]

I tested SLIC for study purpose. Phoenixtool 256 with default settings was successful for b85m-d2v rev3.0. Cert/Slic match verified. Flash successful when Qflash  utility built in BIOS launched. Correct slic visible in RWeverything. Cert install into W7RTMEnterpriseSuccessful.  Key install succesfull, but there is still 30 days to activate. Tested on fresh install with Dell combo of slic/cert/W7Enterp.key, 2nd flash and install of hp combo same , then W7ProSP1 with  w7pro key and same problem. Each case I was waiting overnight, few reboots but nothing helped. If nothing helped I tried slmgr/ato which outputs "inccorect key". I used wide known slp keys which worked on my previous trial cca 6 month ago on another HW.  

Any advice please?

Was anybody succesful activating Win7 with SLP las month or so? Which key, pls? (last few digits)
