[Ccleaner browser opens in Google rather than my specified page]

I installed Ccleaner browser a few days ago and cannot get it to open with my homepage even though I have "New Session" and Homepage set to a specific site.  It insists on opening in Google.  I've double checked all settings and cannot get it corrected.  Any help?  Thanks

[Additional license]

I just purchased Ccleaner for a sales price.  if I want to extend my subscription one additional year, do I buy another license and sit on it for a year or do two licenses stack?

[CCleaner has stopped working]

For some odd reason, my CCleaner Pro is throwing a message when I try to clean:  "A problem caused the program to stop working correctly.  Windows will close the program and notify you if a solution is available."  What gives?  I've uninstalled and reinstalled and still get the error.
