- Crashes may occur when reading in a new XEASY spectrum.
- Try to open the spectrum via Tools->Open Spectrum. This will open a MonoScope window with your spectrum. If you can work normally in this window, the error resides in the Spectrum Type definition. Either you chose a definition not suited to your spectrum or your definitions are faulty.
- If normal work is not possible via Tools->Open Spectrum, have a look at the .param file of the spectrum, especially if it was produced via uxnmr2xeasy. An actual example produced by uxnmr2xeasy is shown below. The example will crash immediately, and even if the first mistake is fixed, Show folded will not work, since CARA needs to know the folding type which is not correctly defined in the example.

If it also fails, this indicates problems with SpectrumType definition. Try to open the same spectrum after loading the most recent Cara template from the TemplatesPage. Try it on another computer or even another operating system.
