I was getting the same hadn't updated since March 30th, I tried downloading latest definitions to install manually which usually work it it wont
I did try stopping MSE altogether to install then restarting No go
To update definitions You can do the following:
1. Unpack mpam-fe.exe package to some folder (using WinRAR or something).
2. Remove MPSigStub.exe from this folder.
3. Unpack mpam-fe.exe revision 1.239.450.0 (or earlier package) to a different folder. Then copy MPSigStub.exe to the first folder with newer definitions.
how do I do this, how do i unpack mpam-fe
4. Run MPSigStub.exe (in the first folder, of course)
after extracting mpam files with 7-zip I don't see a mpam file but I do MPSig
plus other files ending in vdm
what do i do, tried following instructions, now lost
the MPSig file is dated 300317 so looks out of date
I Did even reboot PC and router (which sometimes solves problem) No go
Using XP SP3 here upto now had no problems after putting in reg Posready
