    Not able to launch software. Said “number of Topshim licenses exhausted. You’re trying to run too many copies of this program”

  • Christine says:

    After trying the gradshim command, an error message is coming up (“void shim”? “E3”?)

  • Laura says:

    rga and zg don’t work. I get an error message and no data collection.

  • Adrienne Roehrich says:

    The drx499 is now ready for use with the TXO probe after extended calibrations.

  • Adrienne Roehrich says:

    The drx499 is working per normal function.

  • Steven Adelmund says:

    There is no signal. I noticed the receiver gain was set abnormally high for my samples on HNMR. After processing the data there is only noise. The result is the same even with the dummy sample. The same compounds run fine on AV500.
