I had a similar problem once. I think the only way that i fixed it was to run the o'activate from syzcon.
1. Select File, Run. enter SYZCON as the program name, and click OK.
2. At the prompt, type the following, and press Enter:O = NEW(""SY_ACTIVATION_BUS"",%SYS_SS)
3. At next prompt type the following and press Enter:PRINT O'ACTIVATE(""A/P"",""xxx"") (where xxx = company code)
4. The number 1 is returned if the last command was successful.
5. Type BYE and press ENTER.
