Hi everyone. Was hoping I could get some advice. I purchased the Office Professional 2010 software back in November 2011. I installed it on both pcs as per license allowed. It's been working fine for 2 years. However, my desktop got a virus and I had to reinstall Office. It asked me for the product key up front, then installed successfully. When I open Excel/Word/Access/etc. - I get a window saying the product needs to be activated. I try to activate it and I get an error saying "this product cannot be activated because the product key is invalid". I called Microsoft support and they are telling my product key is invalid and there's NOTHING they can do. I'm furious! I purchased this from MicroCenter in 2011 - brand new. I brought it home and installed it - how could the product key be invalid if I was able to install it then and I've been using the software for 2 years? Has anyone else come across this issue? I'm not sure what to do next and I'm pulling my hair out. I can't take it back to MicroCenter because it's been 2 years and I only keep receipts going back one year. UGH!

Any advice would be soooo appreciated.

THANK YOU
