Anyone else experiencing problems since the last win7 updates?

My Network Admin guru updated win7 a few days ago and now Corel fonts are all out of whack. Everytime I pull up a file from the previous week it tells me the fonts are missing. I go to font navigator and put a checkmark in the look for fonts in the network directory we keeps fonts stored and then it will allow me to install as needed. Now today, I try to pull up a file and says font is missing.

What MS update would have any bearing on Corel unless it did something to the C:/Windows/fonts folder?!
