Can't open macro's in design, Access crashes

[Harry_38]

Extensive Access program with a dozen macros. This morning I tried to open a macro in design, resulting in a crash of Access2010; other macro's also cause a crash when opening. The macro's run ok, without crash.:banghead:

I get the following message on the screen, approx translation inbetween brackets():
