Abstract We construct the two parameter K3 surface and show that there is a point in its moduli space where cycles vanish which do not lead to an enhancement of symmetry in a type IIA superstring. At this point we also find two soliton states which are massless. We then consider a type IIA superstring compactified on K3{times}T{sup 2}. For this theory, the massless solitons belong to an N=2 hypermultiplet because there is no enhancement of gauge symmetry. Thus, the N=4 supersymmetry found when the soliton states are massive, breaks down to N=2 supersymmetry when the soliton states are massless. The renormalization of the gauge couplings confirm this result. {copyright} {ital 1997} {ital The American Physical Society}
