You get them when the code runs that you posted?

Firstly I'd Set Resource Off, or delete foxuser.* respectively.
Then I'd have a look at all involved tables and their CDX files.
Then "dangling references" (although your code snippets do not
look like that).
Then if the C5 exceptions occur on one machine only or on
any PC - if the former, I'd have a look at driver issues - graphics
("Hardware Acceleration"), printers if any.
