My Skype stopped working, need help on fixing it please

I was just wondering why after installing MS Office to my Windows 7 64Bit Version, my Skype stopped working. There should not be any compatibility problems between Skype and MS Office right? I can still log in successfully, can still see who’s online and who’s not but an error message kept me from working ahead. I can’t click into whoever’s name and it is asking me to close the program instead. What should I do?

A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available.
