WUFI

From WUFI Pro 6.5, whenever I select the WUFI Graph icon, it opens Graph and shows it as "F_18.tmp" (or something similar) in the result files window in the top left of the Graph program. I have already saved the WUFI Pro file. If I save the WUFI Graph file, close it and reopen it, it doesn't seem to be able to find the result file. If I want to make any changes to the graphs, I have to start all over. What am I doing wrong?

This may be related: I do not save my Graph files in the local/app data folder that is the default location. I save my files on a company network. Do I have to save everything on to my C:/drive in order to make it work?
Thanks

I figured out the problem, but want to post here for others having the same issue.

I do not have the problem described above when I use the "File">"Open WFUI Results File" command from within WUFI Graph (instead of clicking on the WUFI Graph icon from within WUFI Pro).
