I have an Altalink C8045 at firmware version 101.002.089.22600. The Salesforce app stays stuck on the loading screen for a few minutes then there is a message saying "Variables not defined. Machine must be restarted." Sometimes I also get a message saying "The script on this page appears to have a problem. Do you want to stop the script?" Whether I select yes or no the app force closes itself regardless.
Please give the app another try. I was informed by development that they put in a fix that might fix the issue you are seeing. Please let us know.
