I try to go through the tutorial **Welcome-to-xod**. When turning to the patch **003-inspector** and changing the IVAL value from 1 to 0.1 I ran into to compilation error. Now the error pops up at every simulation. I have tried to reinstall the XOD program but I get the same compilation error all the time. The simulation worked at the beginning (running 002-simulate for the first time) but now: nope ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/e/e4caed73506d44a5ad19c40a93a84f9f9ea493a6.png) What have I done? Or more helpfull; what should I do? I’m using the latest version 0.34 for Windows. ---

Yes, exactly. I have tried to downgrade it to 0.33 but the uninstallation is not clean. It remembers my login and other settings for instance. So I run into the same error there also. ---

Thank you for letting us know. There really was a problem on our backend. The simulations should work now. ---
