Proteus-ISIS Internal Exception error

[18F4520]

Hi, i am getting this strange error:
Internal Exception: access violation in module 'UNKNOWN' 00000000.

It happens when i want to execute conversions library routines from mikroBasic (WordToStr, IntToStr...). I simulate MCU PIC 18F4520.

I have done it before successfully, but now i can't 8-O

So now whenever i put :

in declaration section:

dim aaaa as integer
dim eeee as string[6]

main section:

IntToStr(aaaa, eeee)

I get this error in ISIS.

Any ideas?

Solved:

in declaration section:

dim aaaa as integer
dim aaaa2 as integer
dim eeee as string[6]

main section:

aaaa2 = aaaa
IntToStr(aaaa2, eeee)

Now it works fine.
