There's no reason to be hesitant about asking for help. You're our customer, and we will help as much as we can.
Unfortunately, there are other developers who make other add ons, and sometimes, those other add ons, and the TBM (Not just the TBM, but any aircraft add on) will conflict. This happened with the Saab and XEnviro. We received many complaints from people telling us to fix the Saab and make it run well with XENviro. Even when we went through everything, and determined that the fault lies with XEnviro, people still demanded we fix the Saab.
Eventually, I was able to get a hold of Sergey (XEnviro developer), and after asking him to look into it, even he wasn't convinced. I pleaded with him just to check, so he gathered some users together who also owned the Saab and ran some tests. After less than a day of testing and debugging, he did indeed find a problem with XEnviro. An update was issued soon after, and the incompatibility was resolved.
If the fault lies with the TBM, we will be more than happy to look into it and fix it. However, in many cases, the fault lies with other add ons. Whether it's buggy code or another feature that the TBM already has (An example would be the terrain radar).
All we ask is that people provide log files and go through any steps we ask them to go through.
Again, please don't be nervous/scared/hesitant about asking for help.
