errors in EAs

 
Does anyone know what might be causing the following three errors to happening in an EA?

The first one is from a call to ErrorDescription to print the string associated with the error number. I have been using it for some time on FXDD and IBFX without problems. The errors are from ATC Brokers platform.

First error

07:04:44 myEA_v1_43 GBPUSD,M30: expert function calls are not allowed; 'stdlib'-'ErrorDesc ription'
07:04:44 myEA_v1_43 GBPUSD,M30: expert stopped

Second error

16:46:50 myEA_v1_43 GBPUSD,M30: deinitialized
16:46:50 myEA_v1_43 GBPUSD,M30: uninit reason 4

Third error

17:16:04 myEA_v1_43 GBPUSD,M30: initialized
17:33:28 myEA_v1_43 GBPUSD,M30: deinitialized
17:33:28 myEA_v1_43 GBPUSD,M30: uninit reason 5

These messages were all found in the journal and not printed by me from within the EA.

Thank you.
