This is rather weird, and i hope it can be fixed  cause i can't use the program now.

When i start up Poser 4 i get this error message.

[b]

You are out of memory!!!

Please save your work and quit soon.
You may also need to increase the amount of memory allocated to Poser.[/b]

I have no idea how to do that, i never had to do that before...now..the only real change there has been is that, not so long ago i had to format my PC. But poser is not located on C:/.
It's on my E:/ partition....so when i got windows installed on it again, i still had poser, now  i just wanted to fool around alittle with it, but i get this error. can anyone help me out?

Sounds to me like the format has wiped the registry settings for Poser.  Back up your runtime and reinstall poser

I totally forgot about something else...before i reformatted the pc though, i installed new hardware in my pc as well, how could i forget..cause my motherboard just called it quits, so it's basically a complete new pc, just with the same HDD. So new ram, new CPU, sam GFX card though....ram was 512sdram, now it's 1gb ddr ram.

it may mean it can't find some texture file.

Have you applied the Poser 4.03 memory patch? Poser 4 without the patch cannot handle systems with 1 GB or more memory.
