I upgraded (thanks to the message pop up) from 3.08 to 3.54. Now I get a "Encountered an Improper Argument" window every time I open the Motors and Sensors setup and everytime I click on the Motors tab. This happens with the Sample programs also.
Further the config screen does not show all the motors - just one. The sensors seem to show up correctly. Program compiles without errors.
More worrisome - even the changed Motors setup does not seem to be saved back.

I tried going back to 3.08 but I get a message about newer version should be uninstalled. I am not sure if it is safe to do this because I am not sure how my license would be treated.

Any help?
thanks

For reference; this particular issue was resolved by uninstalling and reinstalling ROBOTC. It was an isolated issue specific to one computer and is not considered a known error with ROBOTC.

Edit: Confirmed bug in ROBOTC 3.54 specific to the PIC platform type; [urlhttp://www.robotc.net/forums/viewtopic.php?f=1&t=5551]fixed in 3.59 BETA[/url] (see below for more information).

John,

I am having exactly the same problem with the 'encountered an improper argument' on 3 computers. I unloaded and reloaded the software but still the same error.
Any other ideas?
Thanks

I have edited my previous post to reflect this, but:

We debugged this issue further and did find this to be an issue with ROBOTC that specifically appeared when trying to change the setup of Motors in the Motors and Sensors Setup window (with PIC as the platform type). Quoted from our 3.59 BETA log:



To solve this issue, take a look at the ROBOTC 3.59 BETA that has the fix implemented. I apologize for any inconveniences this may have caused.

We did switch encoders a while back, our previous one was giving us problems (would return large numbers which would cause our autonomous to be flaky)
Maybe that has something to do with it. Haven't experienced any of the problems with the new one.
