Googling said file extension gives pretty much no good results, with exception of some people asking about mpeg4.srdt files from -12 and -14 with no real answers.
Based on that, said file extension is not normally in use.

Said video files check for license online. As you said, your license is by now expired, thus no license and no video for you.
Bypassing said license check would require you to hack it, which is not supported here.
Conclusion:
It worked before.
license expired
It doesn't work
renew license?

Original place of purchase should tell you what you need to open said video files though.
