Microstation Problem Daily!

We are using Microstation Version SS10 and InRoads Version SS2. 

Cogo Points and alignments/figures are created daily on a huge project. Below is the process and problem.

Process for the day is as follows:

1. Open Microstation>open file
   2. Open InRoads Suite>Open ALG with xin
   3. Work. Creating/editing points, etc.
   4. Save ALG, close InRoads
   5. Save .dgn and save settings (sometimes compress file [have tried compressing before and after closing InRoads during trial and error in finding the root of the problem])
   6. Close .dgn
   
   Next day, when I open Microstation and then the subsequent file, it stays on a grey screen and will not open... corrupt.
   
   To fix, I create a new file and merge to master the previous one (have tried only copying in instead of merging to master). And then sometimes the points I created or edited are lost and must be reassigned thru the Horizontal Curve Set>Events function in InRoads to be relabeled and reassigned.
   
   At the end of the day I have even saved and closed out of everything, then immediately tried re-opening the file I was working in and it opened just fine. Almost as if overnight something is happening.

Has anyone else experienced this problem? If so, what was your solution?

Thanks!
