Hi All, Iam getting Internal Erorr 2 in Module 10 with one of our clients. I tried the following options in the system, Iam getting the error and the Result is as follows.

I try to log-in with diff user id (windows log-in) Navision(userid) It was working perfectly. 2. I tried to use the same log-in(kristin) in other system it works perfectly 3. I deleted the Client Side fin.exe, fin.zup, fin.dmp and Still Iam getting the error… What could be the reason. Can any one help onthis…? Rgds M. Ramanath
