  1. Hi I am currently away from home (abroad) and do not have access to my backups. I properly saved and closed a large design file, and shut down my PC for travelling. When I try to open the file, I get an error "Missing or incomplete GZIP trailer. Expected 8 bytes, got 0." This is a big problem as I need to work on this file. Can anything be done to fix it?
  2. Thanks Martin - I think I've done this before by accident, but forgot where it was. My model (coal mine) WAS about 700 000 branches in 7 stages. I have since reduced it to 135 000 by merging stages and some filtering. I usually just hit F5 (not sure which option this is) - when I select from the Run menu, I use the matrix solver.
  3. Hi all Maybe a silly request, but is there a way to re-open the Network Warnings popup box once you have closed it? I have a bad habit of closing it when it is in the way, and then 1 minute later I want it again, especially while calibrating my model. My model is huge, and the only way I can get it back is to re-solve, which takes several minutes.
  4. Thanks Martin - I will try manually. I have used a company licence for years on the same pc and it hasn't been a problem, although i am now using my own security software. If i let the updater try, it just gives up after a few minutes with no message.
  5. I have purchased a 3-month rental of Ventsim Advanced and am currently on Ver 5.2.9.5. Every time I start the program, it advises that an update is available (5.4), but the software will not update. Are updates not included with rental? Neil Roman
