Hi, I'm using Sage in a commercial environment to perform physics simulations of optical systems. As our computing environment is XP, I'm running Sage on WinXP in VMware Player 3.1.0 build-261024.
This morning, after suspending my machine, the VMware player froze. I had to either power down, or just end the VMware Player. I apologize - I can't recall which. It was right before an important meeting, so things were rather rushed. (What I did *not* do was end VMware Player using the Task Manager). When I restarted VMware Player/Sage, I was unable to access my Sage notebook. If I run the Sage Notebook script, the window closes with some error message to fast to read. If I start up Firefox, I can load internet files. I can also load an HTML version of the notebook I had saved (since I've had Sage clear out the notebook file when the server hangss!). However, if I try to evaluate cells, I get a "Searching for Sage server" message in a red box at the top of the page. I am able to open up the notebook - which, on my system, is at /home/ sage/.sage/sage_notebook.sagenb/home/admin/10/worksheet.html. However, it is now blank (it was not this morning - I've taken to checking because server crashes have previously over-wrtten my running notebook with a blank file: a bug for another day!). However, Firefox cannot find the Sage server. If I start up Firefox, I get a "Service Temporarily Unavailable" message. (The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. Apache/2.2.12 (Ubuntu) Server at localhost Port 80) The usual "Point browser in MS Windows to http://xxx.xxx.xxx.xxx"; message appears. If I start Sage from the command line, I get the following messages: **** Please wait while the Sage Notebook server starts... ...

On a related note, can anyone tell me how to "execute" Sage on my stored HTML (produced by Firefox "Save As" rather than the notebook's "Save" button)? Any help would be greatly appreciated, as the project lumbers on in desperate and immediate need of these optical simulations!
