Memory error
 

New to P99 but originally started in 2001 right after Velious so this is golden. I am getting this memory error and not sure how to remedy. Laptop(HP Pavilon g7 4gb ram) should have plenty of power. It pops up after I login to p99 server "The instruction at 0x101845b4 reference ed memory at 0x01f9f00c. The memory could not read. Click OK to terminate program." Any help please?
