If the rebuild customized options don't work, I've used this to fix a similar error. Sorry if this posts weird, doing this mobile.
Select File, Run. enter SYZCON as the program name, and click OK.
At the prompt, type the following, and press Enter:O = NEW(""SY_ACTIVATION_BUS"",%SYS_SS)
At next prompt type the following and press Enter:PRINT O'ACTIVATE(""I/M"",""xxx"") (where xxx = company code)
The number 1 is returned if the last command was successful.
Type BYE and press ENTER.
