Microsoft Security Essentials expired

Question

I use MS Security Essentials on my Windows 7 x64. I've been using it for years and since a few days now it does not update the definition files.

I tried to do it manually, and I get the following error (translated):

Error code: 0x80070070
Error description: The license for application usage has expired.
The computer is exposed to malware infections.

As much as I know, SE is free to use on an activated Windows and does not expire.

What happened?

It seems that the new definition files take up to 107 MB in file size. I simply has 70 MB of free space on my C drive and it is not enough...

After freeing up some space, SE could update itself. Great...
