I am troubleshooting a problem with one single excel file on one single computer. This is a small business with a network to a internal storage device. The excel file is updated monthly with expenses. When trying to access it recently, it opens, but the page looks blank. The file lists 12.8 kb of content. If you insert a pic, it acts like it did, does not show the pic, and asks if you want to save your changes when closing the file. the file was able to be seen previously, and any other excel file opens normally. If this same file is sent to another computer in the company, it opens fine and can be seen. We have tried to open the source file saved on the network, and same results. This is office 2010 pro.
