 - Crashes may occur when reading in a new XEASY spectrum. 

    1. 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.

    2. 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.
<pre>                    Spectrometer frequency in w3 .. 750.130005

                    Folding in w1 ................. NO <------------- Should be RSH, ... !!!
                    Folding in w2 ................. NO
                    Folding in w3 ................. NO
                    Type of spectrum .............. ?
                    Identifier for dimension w1 ... N
                    Identifier for dimension w2 ... C
                    Identifier for dimension w3 ... H</pre>
    
    3. Trouble-shooting: Try to open another spectrum of the same type. If it also fails, this indicates problems with "SpectrumType":CreateSpectrumType 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.
