Ok, so here are some facts.
- The last offline version, as a file that I have generated is months old.
- Previous versions were identical, because I used third-party software to build fxdreema.exe and this software has not been updated for years.
- Many people are using the offline version and I have never seen problem like yours, but I noticed more problem reports with the keyword "Windows 10" in the las days.
- Interesting fact, I was one of the first people who decided to install Windows 10 when it was in early testing stage (September last year). In December/January I was losing so much time while trying to deal with Windows 10 issues, so I just decided to move back to Windows 8. At that time MetaTrader 4 was not able to run at all, even in the early days when Windows 10 was released. In short, Windows 10 is just buggy.
- Normally I would love to try everything new, but when it comes to Windows 10, I don't even want to know that it exists.
I can't even imagine how "Buy pending order" can break the offline version, all blocks are identical in the way they are loaded and this one contains nothing special. I have no idea what is going on. But the biggest "problem" is that I currently have no plans to update the offline version
I'm still waiting for new version of the third-party software that I use to pack fxdreema.exe, but meanwhile I decided to move to leave PHP in the past and work on Node.JS, so I will probably now start to rewrite fxDreema for Node.JS and who knows about the offline version... I never liked it anyway.
If you use TeamViewer I can take a look, otherwise I don't know what to do, because I can't fix something that I don't know what it is 
There is still online version and when some problem happens, I react quickly to fix it. Well, it's probably a little bit slower that the offline version and sometimes reload is needed, but it works. And now contains more stuff than the offline version.
