source sdk trouble

[mangaka92]

hey i am having a problem with source sdk.i had my computer reformated so i had to re-install source sdk, half life 2, and half life 2 deathmatch, but when i go to open deathmatch it gives me a message saying

the instruction at "0xoe7e915b" referenced
memory at "0xoe7e915b". the memory could
not be "read"
click on OK the terminate the program

same thing happens when i try to start a new map in hammer editor.hammer opens fine, but i can open or start a new map without getting that error and having it close down.
if anyone could help i would really appreciate it.thanks

First of all, try reinstalling or confirming the integrity of game cache. Sounds like something wasn't installed during installation.
