Unable to launch SolveigMM Video Splitter Home Edition 7.0

I uninstalled and re-installed the program without success. Then I checked my Comodo firewall and removed references
to Solveig. I launched the program again, and entered 'Trusted application' into Comodo when asked. This time it was
successful, and no license verification appeared. Hopefully it has solved the problem.

Sorry, I forgot to mention that it's the paid version.

I'm running this version with Windows 7 as I find it easier to use than the upgrades.
Recently, when the program opens, a box pops up, saying:

To verify your license internet is required.
Program will stop working without verification.
Days left:

It gives me 2 options; Verify (which it has accepted in the past), or Close.
But now, the program will close whichever option I choose, and
there is no way of closing the box and checking out the Tools or Help.

What can I do, short of reinstalling and seeing what happens.
